If X = 4 then 5X is equal to 5 x 4 which is 20. So 20 + 2 = 22.
5x + 3 = 6x + 1 Subtract 5x from both sides: 3 = x + 1 Subtract 1 from both sides: 2 = x
y = 5x + 3When x=2,y = 5(2) + 3 = 10 + 3 = 13
There are 2 unknowns
Add 4x - 2 to each side: 5x = 5 x = 1
8x-7 plus 2x equals 6 plus 5x plus 2?
f(x)=5x+2
5x+2=x+10 5x-x=10-2 4x=8 x=2

Here is the work for that problem: 5x+ 2=12 5x= 12-2 5x=10 x= 2
x=6Solution:x + 2x + 14 = 5x + 214 - 2 = 5x - 3x12 = 2xx = 12/2 = 6
5x+2=2x-10 x=-4
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
x = zero
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
x = -1.4
If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.
