Question

4x - 5y = 14

If y = 2, what value of x satisfies the given equation?
A) 6
B) 8
C) 10
D) 24

Answer 1

A

Explanation:

Given

4x - 5y = 14 ← substitute y = 2 into the equation and solve for x

4x - 5(2) = 14, that is

4x - 10 = 14 ( add 10 to both sides )

4x = 24 ( divide both sides by 4 )

x = 6 → A
