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
