Answer 1

A) 7x=7, x = 7/7, x=1.
B) 0=2 - 2x, 2x = 2, x =2/2, x=1.
C) 8x+2x = 6 + 4, 10x = 10, x=1.
D)2x+8x = 6 + 4, 10x= 10, x=1.
E) 18=16x+2x, 18 = 18x, 18x = 18, x = 1.
F)8x + 4x - 3x = -6-8, 9x = -14, x= -14/9.

Answer 2

A) 5x + 2x = 4 + 3
7x = 7
x = 1

B) -6 + 6 = 2 - 2x
0 - 2 = -2x
-2x = -2
x = 1

C) 8x - 4 = 6 - 2x
8x + 2x = 6 + 4
10x = 10
x = 1

D) -4 + 2x = 6 - 8x
2x + 8x = 6 + 4
10x = 10
x = 1

E) 12 + 6 - 2x = 16x
18 - 2x = 16x
16x + 2x = 18
18x = 18
x = 1

F) 8x + 4x + 8 = 3x - 6
12x + 8 = 3x - 6
12x - 3x = -6 - 8
9x = -14
x = -14/9
