Question

1)3x-2=5x-3 2) 8-2x=8-4x 3)3(x-2)=7(x-3) 4)6x-3=(8-x)3
5)3x/2-8=5x/4-3 ???

Answer 1

1)
3x -5x = -3 +2
-2x = -1
(-1) -2x = -1 (-1)
+2x = +1
x = 1/2 (1 sobre 2)
x= 2

2)
-2x +4x = 8 - 8
+2x = 0
x= 0/2 (0 sobre 2)
x= 0

3)
3.x - 3.2 = 7.x - 7.3
3x -6 = 7x -21
3x -7x = -21 +6
4x = -15
x= 15/4 (15 sobre 4)
