63 x 42 = 2646

       63

x     42

     126

+ 252

   2646

I am sure you will get it!

Just focus, and keep trying.

10m – 2 = 9m – 14

Subtract 9m from both sides.

10m - 9m – 2 = 9m - 9m – 14

Solve.

m - 2 = (-14)

Add 2 to both sides. (Do the opposite of the sign it shows. Negative = Positive. Times = Divide)

m - 2 + 2 = (-14) + 2

Solve.

m = (-12)

Always make sure m positive. 

I will show you!

Sure!

-19y = -15 – 16y

First, add 16y to the left side and the right side.

-19y + 16y = -15 - 16y + 16y

This cancels out - 16y from the left, making it easier to solve.

-3y = -15y

Change both signs to a positive (Only if both sides are negative or already positive)

3y = 15

Divide by 3 on both sides.

3y/3 = 15/3

Solve.

y = 5

When you divide 3y by 3, it cancels out the three, because 3/3 is 1, and 1y = y.

So your answer is y = 5

8x2/3

8x2 = 16

16/3 = 5.33333

OR

5 1/3

7n - 5n – 18 = 14 + 5n - 5n

2n - 18 + 18 = 14 + 18

2n/2 = 32/2

n = 16

Really? I learned this just last week, I am in Algebra 1 in 7th Grade =P

You're welcome! 

6u + 15 = 11u

-6u          -6u

15/5 = 5u/5

3 = u
