Solve each of the following equations.a. 8 + 2x = 3x- 7Answer: ___________b. 2a- 1 = 10a- 9Answer: ___________c. 9 - 3x = -7x- 7Answer: ___________
What will be an ideal response?
a. 8 + 2x- 2x = 3x- 2x- 7
8 + 7 = x - 7 + 7
15 = x
b. 2a - 2a - 1 = 10a- 2a- 9
-1 + 9 = 8a- 9 + 9
8/8 = 8a/8
1 = a
c. 9 - 3x + 3x = -7x + 3x- 7
9 + 7 = -4x- 7 + 7
16/-4 = -4x/-4
-4 = x
