Solve each of the following.a. 5(2a- 3) = 5a + 5Answer: ___________b. 2(4 + x) = 3x- 5Answer: ___________c. 2(-x + 5) = 2(x- 9)Answer: ___________
What will be an ideal response?
a. 5(2a- 3) = 5a + 5
10a- 5a- 15 = 5a - 5a + 5
5a- 15 + 15 = 5 + 15
5a/5 = 20/5
a = 4
b. 2(4 + x) = 3x- 5
8 + 2x- 2x = 3x- 2x- 5
8 + 5 = x- 5 + 5
13 = x
c. 2(-x + 5) = 2(x- 9)
-2x + 10 = 2x- 18
-2x + 2x + 10 = 2x + 2x- 18
10 + 18 = 4x- 18 + 18
28/4 = 4x/4
7 = x
