X is the number

when x is decreased by 18, we say 18-x

the result is 14

18-x=14
minus 18 both sides
-x=-32
times both sides by -1
x=32

equation has infinitely many solutions has the same number on both sides of the equal sign

-3x -21 + x + 5 = -20x -16

-2x -16 = -20x -16

so either you have -18x on the left or +18x in the right
