Question

2x+2y= 24 x=3y What is the value of x+y? I WILL MARK BRAINLIEST AND GIVE 20 POINTS.

Answer 1

Since this is a system of equations, substitute the value of x into the other equation.

2(3y)+2y=24
6y+2y=24
8y=24
y=3

x=3(3)
x=9

To check my work, substitute my x and y values:
2(9)+2(3)=24
18+6=24
24=24

Your answer is (3,9)

Hope this helps! Have a wonderful day :)
