Find the solution of this system of equations 2x-4y=32 <br> 2x-8y=48
EleoNora [17]
2x - 4y = 32
2x - 8y = 48

2x - 2x - 4x - (-8y) = 32 - 48

4x = -16
x = -16 ÷ 4
x = -4

substitute your value of x into any of the original equations

2 (-4) - 4y = 32

-8 - 4y = 32

-4y = 32 + 8

-4y = 40
y = 40 ÷ -4
y = -10

What is the answer to 3x+y=12
maw [93]
<span>Simplifying 3x + -1y = 12 Solving 3x + -1y = 12 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add 'y' to each side of the equation. 3x + -1y + y = 12 + y Combine like terms: -1y + y = 0 3x + 0 = 12 + y 3x = 12 + y Divide each side by '3'. x = 4 + 0.3333333333y Simplifying x = 4 + 0.3333333333y</span>
