If you mean: 5x = 10 then the value of x is 2
The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8

5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
3 + 5x = 38 -> 5x = 35 -> x = 7
If you mean 5x+2 = 12 then 5x = 10 and the value of x is 2
When x equals 8, the value of 5x would be 5 times 8, which is 40.
if y = 5x – 8 find the value of x if y = 7
If you mean: 7x-2 = 5x+16 then the value of x works out as 9
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3

The variables have no known values and as an expression it is: 5x+9y+5
If you mean 5x+4x = 54 then the value of x is 6
If you mean: 7x-2 = 5x+16 then the value of x works out as 9
