I am guessing that you are looking for the value of "x"!
Here we go :
18x - 2(3x + 1) = 5x - 16
Let's start with the parentheses :
-2 × 3x = -6x
-2 × 1 = -2
18x - 6x - 2 = 5x - 16
subtract 6x from 18x
12x - 2 = 5x - 16
add 2 on both side of the equation
12x = 5x - 14
subtract 5x from both side of the equation
7x = -14
divide by 7 on each side of the equation
x = -2
There you go! I really hope this helped, if there's anything just let me know! :)
