If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−3x+27
126−3x+27
Add the numbers
153−3x
153−3x=0
Move the constant to the right-hand side and change its sign
−3x=0−153
Removing 0 doesn't change the value,so remove it from the expression
−3x=−153
Change the signs on both sides of the equation
3x=153
Divide both sides
33x=3153
Divide the numbers
x=3153
