Solve for  x .

2x + 9  =  35           Subtract  9  from both sides of the equation.

2x  =  35 - 9

2x  =  26                 Divide both sides of the equation by  2  .

x  =  26 / 2

x  =  13

 

Solve for  p .

3 + |1 + p|  =  12

I don't really know the best way to do these, but someone else probably does.  smiley

 

Solve for  n .

(2n - 3) / 5  =  5         Multiply both sides of the equation by  5  .

2n - 3  =  5 * 5

2n - 3  =  25              Add  3  to both sides of the equation.

2n  =  25 + 3

2n  =  28                   Divide both sides of the equation by  2  .

n  =  28 / 2

n  =  14

 

Solve for  d .

6(d + 1) - 2d  =  54       Distribute the  6  to both terms in parenthesees.

6d + 6 - 2d  =  54         Combine  6d  and  -2d  to get  4d  .

4d + 6  =  54                Subtract  6  from both sides.

4d  =  48                      Divide both sides by  4  .

d  =  12

 

Solve for  y .

-140  =  18 + 4(5y - 2)          Distribute the  4  to both terms in parenthesees.

-140  =  18 + 20y - 8            Combine  18  and  -8  to get  10  .

-140  =  10 + 20y                 Subtract  10  from both sides.

-150  =  20y                         Divide both sides by  20  .

-7.5  =  y
