Answer: x = 10; y = 32
Step-by-step explanation:
let −5x+2y=14 be [1]
& y=3x+2 be [2]
Finding the value of x
By substituting y in [2] for y in [1]
⇒ −5x + 2(3x+2) = 14 [expand the bracket]
⇒ -5x + 6x + 4 = 14 [subract 4 from both sides and simplify]
⇒ x = 10
Finding the value of y
Since x =10, we can substitute value of x into [2]
⇒ y = 3(10) + 2
⇒ y = 32
