If x equals 8, then 3x equals 24. 24-x would equal 16.
3x-x = 2x. So when x = 8, 3x-x = 2*8 = 16
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
8
-4. x=2
3x - 4 = 83x = 8+43x = 12x = 12/3 = 4
8
3x - x = 3*8 - 8 = 24 - 8 = 16
3x + 8 = 20 - 3x 6x = 12 x = 2
3x + 8 = 8 Therefore, 3x = 0 x = 0/3 x = 0
3x-12=12 express the equation in terms of x, 3x=12+12 then, perform the operation 3x=24 x=8 that is now the value of x.
Are you asking how to find the value of x? If so: 3x-3 = x+5 3x-x = 5+3 2x = 8 x = 4
3x=24 x=8
