Question

Chase was trying to solve for x and y. He knows that the value of x is 3 times the value of y and that half of x plus twice y is equivalent to -14

Answer 1

the answer should be A

Explanation:

Answer 2

the value of x is -12 and the value of y is -4

Explanation:

Given;

x = 3y ----- (1)

`(x)/(2) + 2y = -14` ----(2)

Substitute the value of x into equation (2)

`(3y)/(2) + 2y = -14\\\\multiply \ through \ by \ 2\\\\3y + 4y = -28\\\\7y = -28\\\\divide \ through \ by \ 7 \\\\y = -4\\\\solve \ for \ x\\\\x = 3y\\\\x = 3(-4)\\\\x = -12`

Thus, the value of x is -12 and the value of y is -4
