You are given two algebraic equations, y = 3x, and 2y = x + 20. Solve for x and y.
Yuri [45]

Answer:

x= -4 & y=-12

Step-by-step explanation:

multiply y=3x by 2

giving you 2y=6x

subtracting 2y=x+20 from 2y =6x

=> 5x=-20

dividing through by 5

=> x=-4

put x=-4 into y=3x

=> y=3(-4)

<em>y</em><em>=</em><em>-12</em>
