A. 7x = -3( 2-2x)
B. X = -3 (5x+4)
C. -7( 3x+3) = 21
D. 3(2x-3) = -4 (x+1)
E. 5x+7 = -5 (2-x)
F. -2(x-1) = -3 (x+2)
G. 2(4x-1) = -38
H. -8(x+1) = -3 (3x+2)
I. 5(2x-1) -4 = -3 (-2x+2)
J. 3(-4x-9) = -3 (2x+9)
K. 5-4(x-6) = -3 (x+2)
L. 5(3x-1) = -3 (6x+2)​

Answer 1

A)

7x = -3 . (2 - 2x)

7x = -6 +6x

7x - 6x = -6

1x = -6

x = -6 : 1

x = -6
