Multiply the first equation by 2 and add the new equation to the second equation.

-11x + 7y = 20

Step-by-step explanation:

See image. Multiply

2(-2x + 2y = 16)

You get -4x + 4y = 32

Then line that guy up underneath the

-15x + 3y = -12. You're adding vertically from the top down, x's with x's and y's with y's and plain numbers with plain numbers. See image

42%

step-by-step explanation:

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
