Question

2x+3 +7=-7x

-----    --   ---

   4      4     5

Answer 1

First, find the LCD of the equation.  The LCD is 20.

 

Multiply both sides of the equation by 20 to get rid of denominator.

 

5(2x + 3) + 5(7) = 4(-7x)

 

 

Distribute to get rid of parentheses.

 

10x + 15 + 35 = -28x

 

 

Now you can solve this equation.
