Answer:
x = 1
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
here k = 8, thus
y = 8x ← equation of variation
When y = 8, then
8x = 8 ( divide both sides by 8 )
x = 1
We have:
5(x + 7) = 85 |divide both sides by 5
x + 7 = 17 |subtract 7 from both sides
x = 10
