Question

1/5x-2/3y=30
What is the value of the x in the equation when y=15

Answer 1

x = 200

Explanation:

1/5x-10=30 (2/3y will equal 10 if it y=15)

Add 10 on both sides

1/5x=40

Times 5 on both sides

x = 200

Answer 2

`(1)/(5) x - (2)/(3) y = 30 \\ (1)/(5) x - (2)/(3) 15 = 30 \\ (1)/(5) x - (30)/(3) = 30 \\ (1)/(5) x - 10 = 30 \\ (1)/(5) x = 30 + 10 \\ (1)/(5) x = 40 \\ x = 40 / (1)/(5) \\ x = 40 * (5)/(1) \\ x = 40 * 5 \\ x = 200`
