Subtract the numbers
24−6x
24−6x−6=0
Subtract the numbers
18−6x=0
Move the constant to the right-hand side and change its sign
−6x=0−18
Removing 0 doesn't change the value,so remove it from the expression
−6x=−18
Change the signs on both sides of the equation
6x=18
Divide both sides
66x=618
Divide the numbers
x=618
