4x-2y=8
x-3y=-3
Multiply equation 2 by 4;
4x-2y=8
4x-12y=-12
Subtracting equation II from equation I;
10y=20
y=2
Replacing the value of y in equation;
4x-2y=8
4x-2(2)=8
4x-4=8
4x=12
x=3

Step-by-step explanation:

This is because you take 18x100(100 is the total % under 72 because 72 is out of 100) that equals 1800. then, you take 1800 and divide it by 72. That is because 72 is the actual number that we already have. You would get 25 after dividing. hope this helps:)
