5x=11y
-43
4x-7=5x-2 x=-5
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.
If X = 5, then 5X = 5 x 5 = 25
X=5
If X = 9 then 5X would = 5 x 9, which is 45.
128
x-5x=4.5 -4x=4.5 x=-1.125
When x equals 8, the value of 5x would be 5 times 8, which is 40.
X=122.2
5x - 8 = 717 5x = 725 x = 725/5 x = 145
