x = 31
When x equals 8, the value of 5x would be 5 times 8, which is 40.
x-5x=4.5 -4x=4.5 x=-1.125
x = 5.4
5x-3 = 37 5x = 37+3 5x = 40 x = 8

x = 31
When x equals 8, the value of 5x would be 5 times 8, which is 40.
x-5x=4.5 -4x=4.5 x=-1.125
5x+10=40 5x+10-10=40-10 5x=30 5x/5=30/5 x=6
x = 5.4

If: 3x-7 = 5x+13 Then: x = -10
3x + 2x = 40 5x = 40 x = 8
X = 10
