The value of x works out as 10
you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
That depends on what the value of x is.
The expression "5x plus 8" can be represented mathematically as (5x + 8). The value of this expression depends on the value of (x). If you provide a specific value for (x), I can calculate the corresponding value of (5x + 8) for you.
x-5x=4.5 -4x=4.5 x=-1.125
3 + 5x = 38 -> 5x = 35 -> x = 7
you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
y = 5x is the equation of a line. Subtitute any value for "x", then calculate the corresponding value of "y", which in this case is simply the value of "x" multipled by 5.

3x = 7-5x 8x=7 x = 7/8 x = 0.875
x-5x=4.5 -4x=4.5 x=-1.125
5x = 5 times 9, 2y = 2 times 4 so 45 - 8 ie 37
5x-2x=9
3 + 5x = 38 -> 5x = 35 -> x = 7
When x equals 8, the value of 5x would be 5 times 8, which is 40.
x = 31
