If 3x + 5x = -8, what is x + 1? 3x + 5x = -8 8x = -8 x = -1 x + 1 = -1 + 1 = 0
If you mean 5x+4x = 54 then the value of x is 6
-5x+2=-6+x therefore -5x+2+6=x therefore 2+6=x+5x therefore 8=6x therefore 8/6=x therefore x=4/3=1.3333

5x = 5 times 9, 2y = 2 times 4 so 45 - 8 ie 37
When x equals 8, the value of 5x would be 5 times 8, which is 40.
you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
if y = 5x – 8 find the value of x if y = 7
5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
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
The value of x is 4.2

x + 5x + 6x = 12x. There are 3 terms. If the arithmetic mean is 8 then 12x = 3 x 8 = 24 : So, x = 24 ÷ 12 = 2.
5x=4012y=84124
6x - 3x = 5x - 10x + 12 6x - 3x - 5x + 10x = 12 8x = 12 8x/8 = 12/8 x = 12/8 = 3/2 x = 1.5
It is an equation and the value of x is 8
5x+8 = 10x+35x-10x = 3-8-5x = -5x = 1 and by substituting the value of x into the equations y = 13
