When x equals 8, the value of 5x would be 5 times 8, which is 40.
If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.
5x+y = 2 5x-3y = 14 Subtract the bottom equation from the top equation: 4y = -12 y = -3 Substitute the value of y into the original equations to find the value of x: So: x = 1 and y = -3
5x=4012y=84124
