5x+2=x+10 5x-x=10-2 4x=8 x=2
2
5x=10 5x/5=10/5 x=2
-4 5x + 2 = -18 0x + -2 = -2 ---------------- 5x + 0 = -20 5x / 5 = -20/5 x = -4
If: 5x/10 = 2 then the value of x works out as 4
4x-7=5x-2 x=-5
5x+2=x+10 5x-x=10-2 4x=8 x=2
f(x)=5x+2
x = zero
2
5x=10 5x/5=10/5 x=2
5x-5 = -3 5x = -3+5 5x = 2 x = 2/5
5x-3=2-8x 5x-3+3=2-8x+3 5x=5-8x 5x+8x=5-8x+8x 13x=5 x=5/13
-4 5x + 2 = -18 0x + -2 = -2 ---------------- 5x + 0 = -20 5x / 5 = -20/5 x = -4
x=2 y=7 5x+3y= 5 7 x 2 x 3 ____ _____ 10 21 21 + 10 _______ 31
If: 5x/10 = 2 then the value of x works out as 4
Here is the work for that problem: 5x+ 2=12 5x= 12-2 5x=10 x= 2
