Question

Find the value of r in the equation below, giving your answer as a decimal. 10r + 6 = 49 r = ...​

Answer 1

R=4.3 or 43/10

Explanation:

10r + 6 - 6 = 49 - 6 subtract 6 from each side of equation

10r = 43

10r/10 = 43/10 divide each side by 10

r = 43/10 or 4.3 or 4 3/10 as mixed number

Answer 2

r = 4.3

Explanation:

10r + 6 = 49

subtract 6 from both sides:

10r = 43

divide both sides by 10:

r = 4.3
