Solve for s.

1/2 s =7/2

A s= 1/7

B s=2/7

C s= 3

D s =7

To solve this equation, first get rid of the fractions.

We do this by multiplying both sides by the denominator, 2.

So we have (2)(1/2s) = (7/2)(2).

On the left, we have s and on the right, we have 7.

So we have s = 7.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
