Solving for x in the literal equation cx + 7  =  3:

Subtract 7 from both sides:                 cx  =  -4

Divide both sides by c:                         x  = -4/c

I think that ou should slightly change it because an exponential equation has a variable as an exponent.

If you change it to:  3^x = 27 and then show that since 27 = 3³,  3^x = 3³ which shows that x = 3.

Since there so many 3s in that explanation, I suggest that you might use:  2^x = 32  and since 32 = 2⁵,  2^x = 2⁵, which shows that x = 5.

what is the answer to this 14=8+j=14-8=j=6, so

j=6

x^10 X x^8=x^18

-50r = 1    divide both sides by -50

r = -1/50

Here is your answer step by step:

Solve for n:
-6 = (3 n)/7
Reverse the equality in -6 = (3 n)/7 in order to isolate n to the left hand side.
-6 = (3 n)/7 is equivalent to (3 n)/7 = -6:
(3 n)/7 = -6
Multiply both sides by a constant to simplify the equation.
Multiply both sides of (3 n)/7 = -6 by 7/3:
((7×3 n)/(3))/(7) = -6×7/3
Express 7/3 (-6) as a single fraction.
7/3 (-6) = (7 (-6))/3:
(7×3 n)/(3×7) = (-6×7)/3
Cancel common terms in the numerator and denominator of (7×3 n)/(3×7).
(7×3 n)/(3×7) = (3×7)/(3×7)×n = n:
n = (-6×7)/3
In (7 (-6))/3, divide -6 in the numerator by 3 in the denominator.
(-6)/3 = (3 (-2))/3 = -2:
n = 7×-2
Multiply 7 and -2 together.
7 (-2)  =  -14:

-4-X=19

-x=19 + 4

x= -23

8 1/3 - 4 3/4

=43/12=3 7/12

your answer would be 19

-2 1/2 + (-3 3/4)=-25/4

-15=-11+v, move all the numbers to one side and change the sign from- to +, thus:

11-15=v

-4=v, or

v=-4

4x^2+56x+196=0

x= -7, here is step by step solution:

Solve for x over the real numbers:
4 x^2+56 x+196 = 0
Write the quadratic equation in standard form.
Divide both sides by 4:
x^2+14 x+49 = 0
Factor the left hand side.
Write the left hand side as a square:
(x+7)^2 = 0
Eliminate the exponent on the left hand side.
Take the square root of both sides:
x+7 = 0
Solve for x.
Subtract 7 from both sides:

| x = -7

You can get a sum of 23 by selecting a 5 from the first set and an 18 from the second set

                                     or selecting a 9 from the first set and a 14 from the second set.

The probability of selecting a 5 from the first set is 1/4 and the probability of selecting an 18 from the second set is 1/5, so the probability of selecting a 5 from the first set and an 18 from the second set is  1/4 x 1/5  or  1/20.

The probability of selecting a 9 from the first set is 1/4 and the probability of selecting a 14 from the second set is 1/5, so the probability of selecting a 9 from the first set and a 14 from the second set is  1/4 x 1/5  or  1/20.

The probability of doing either of these two is found by adding the individual probabilities together:  1/20 + 1/20  =  1/10.

The answer is 1/10.

-15  =  -11 + v

To remove the  -11 from the right side of the equation, add  11  to both sides:  -15 + 11  =  -11 + 11 + v

Since  -15 + 11  =  -4,                                                                                          -4  =  v

Divide by -50
