Question

What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15?

Answer 1

Answer:

x = 200

Step-by-step explanation:

substitute y = 15 into the equation

$\frac{1}{5}$ x - ($\frac{2}{3}$ × 15) = 30

$\frac{1}{5}$ x - 10 = 30 ( add 10 to both sides )

$\frac{1}{5}$ x = 40 ( multiply both sides by 5 to clear the fraction )

x = 5 × 40 = 200
