Answer,
S = -16
Explanation,
Step 1: Simplify both sides of the equation.
13 + 11s = − 15 + 8s − 20
13 + 11s = − 15 + 8s + − 20
11s + 13 = (8s) + (− 15 + − 20) (Combine Like Terms)
11s + 13 = 8s + − 35
11s + 13 = 8s − 35
Step 2: Subtract 8s from both sides.
11s + 13 − 8s = 8s − 35 − 8s
3s + 13 = − 35
Step 3: Subtract 13 from both sides.
3s + 13 − 13 = − 35 − 13
3s = − 48
Step 4: Divide both sides by 3.
3s/3 = −48/3
s = -16
Hope this helps :-)
