First, multiply by Start Fraction 1 over 3 End Fraction , then subtract 4.
First, distribute the 3, then add 12, and lastly divide by 3.
The operation that should be done first when solving the equation -12(x+10)=-3 is to divide by -12.
The next step, which would simplify the equation before solving for the variable, is to combine like terms in parentheses.
