-3(x - 2) - (2x - 3) = 5 - (4x - 2)
STatiana [176]

Answer:

x=2

Step-by-step explanation:

-3*(x-2)-(2*x-3)-(5-(4*x-2))=0

((0 -  3 • (x - 2)) -  (2x - 3)) -  (7 - 4x)  = 0

2 - x  = 0

-x+2 = 0

Subtract  2  from both sides of the equation :

                     -x = -2

Multiply both sides of the equation by (-1) :  x = 2
