(x + 20) - 2 + 5x = -18
x + 20 - 2 + 5x = -18
6x -+18 = -18
6x = -36
x = -6

x+20-2+5x= -18 Add the variables and the numbers together
6x+18= -18 Subtract 18 on both sides
-18= -18
6x= -36 Divide by 6
6 6
Answer x= -6
Check:
x+20-2+5x= -18 Plug in -6
-6+20-2+5(-6)= -18
12+(-30)= -18
-18= -18

x + 20 - 2 + (5 * x) = -18
x + 19 + 5x = -18
combine like terms:
6x = -36
divide both sides by 6:
x = -6
Check your work, plug in "-6" into original question:
-6 + 20 - 2 + (5 * -6) = -18
12 - 30 = -18
-18 = -18 this appears correct
The only tricky part of this problem is to make sure you
follow the correct "order of operations" -- that multiplication and division are calculated before addition and subtraction.

sume of x and 20 = (x+20)
minus 2 = (x+20)-2
pluse product of 5 and x= (5x)+(x+20)-2
therefore the whole thing is:
6x+18 and it is equal to -18:
6x+18=-18 => 6x= -36 => x=-6

(x+20-2)+(5*x)=-18
(x+18)+5x=-18
6x+18=-18
6x=-36
x=-6
That's assuming I read your problem right, of course...
