What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15? 4 8 80 200
vova2212 [387]

Answer:

x = 200

Step-by-step explanation:

Given

\frac{1}{5} x - \frac{2}{3} y = 30 ← substitute y = 15 into the equation

\frac{1}{5} x - \frac{2}{3} × 15 = 30 , that is

\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 = 200
