Find the solution of this system of equations -4x-y=-18 -7x+y=-4

x = 2, y = 10

Step-by-step explanation:

Use elimination to take out one of the terms and solve for the other.

In the image below, I eliminated y and solved for x first, where I got -11x = -22 and divided both sides by the coefficient before x, -11, to get x = 2.

I then plugged in x = 2 to one of the equations. I used -4x - y = -18 and plugged in my x value, which simplified it to -y = -10. This simplifies to y = 10.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
