To solve you move the variables to the side and divide both sides by the factor number that doesnt have the variables your answer would be b=23/2 as a decimal is 11.5
Answer:
b = 23/2 or b = 11.5
Step-by-step explanation:
STEP 1: Simplify both sides of the equation.
1/2(4b - 6) = 20
(1/2)(4b) + (1/2)(- 6) = 20 (DISTRIBUTE)
2b + - 3 = 20
2b - 3 = 20
STEP 2: Add 3 to both sides.
2b - 3 + 3 = 20 + 3
2b = 23
STEP 3: Divide both sides by 2.
2b/2 = 23/2
b = 23/2
