Question

Carol is 66 inches tall this is 20 inches less than 2 times mind's height how tall is mindy

Answer 1

66+20=86
86 divided by 2= 43
Mindy is 43 inches tall

Answer 2

66 + 20 = 86
86 ÷ 2 = 43
43 inches

Algebraically is represented as 66 = 2x - 20
The 66 represents Carol's Height
Mindy's Height is represented by x
So 2 of Mindy's heights minus 20 inches is Carol's Height

66 = 2x - 20
86 = 2x (Add 20 to both sides)
43 = x (Divide both sides by 2)
