5x-(7x-4)-2=5-(3x+2)

Question

5x-(7x-4)-2=5-(3x+2)

Answer 1

 

5x - (7x - 4) - 2 = 5 - (3x + 2)

 

Use distributive property to expand

 

5x - 7x + 4 - 2 = 5 - 3x - 2

 

Combine like terms ... isolate the variable on 1 side of the equation

 

-2x + 2 = 5 - 2 - 3x

-2x + 2 = 3 - 3x

-2x +3x = 3 - 2

x = 1

 

 

CHECK:

 

5(1) - (7((1) - 4) - 2 = 5 - (3(1) + 2)

5 - 3 - 2 = 5 - 5 - 5

2 - 2  =  0

0 = 0
