Question

Given that R = 9 x + 8 y Find x when y = 8 and R = 4

Answer 1

- 20/3 = x Step -by - step explanation : Substitute the values that you were given in for the variables : 4 = 9x + 8(8) - Subtract 64 from both 4 = 9x + 64 sides - Divide both sides by 9 to - 60 = 9x get x by itself - - 60/9 = x Simplify - 20/3 = x

Answer 2

-20/3 = x

Explanation:

Substitute the values that you were given in for the variables:

4 = 9x + 8(8)

4 = 9x + 64 - Subtract 64 from both sides

-60 = 9x - Divide both sides by 9 to get x by itself

-60/9 = x - Simplify

-20/3 = x
