Question

If y=36 when x=6 find x when y=42

Answer 1

X = 7

Explanation:

The proportion is 6:1 so if you do 42 / 6 you get x =7

Answer 2

x = 7

Explanation:

First, solve by dividing y with x

When x = 6, y = 36

36/6= 6

6(x) = y is your equation.

Now plug in 42 for y

6(x) = 42

Isolate the x. Divide 6 from both sides

(6x)/6 = (42)/6

x = 42/6

x = 7

7 is your answer for x.
