Answer 1

A. 1,5x = 6
X = 4

B. 8x - 5x = 4,5
3x = 4,5
X = 1,5

C. 2,5x - 5 = 1,5x + 1
2,5x - 1,5x = 5+1
X = 6

D. 3,5x + 8 = 2x - 14
3,5x - 2x = - 14 - 8
1,5x = - 22
X = 14,666...

3.A. 4x + 4 = 12
4x = 8
X = 2

B. 9x - 27 + 1 = 18
9x = 54
X = 6

C. 15 - 5x = 4x + 18
-9x = 3
X = - 1/3

D. 6x - 3 = - 2x - 6
8x = - 3
X = - 3/8

E. 3x - 6 - 5x + 5 = 7
-2x = 8
X = - 4
