210 is equal to the total of p and 111

p + 111 = 210

p = 99

Step-by-step explanation:

Break the question down into parts.

Convert each part into algebraic form (numbers or symbols).

210                                =>   210

is equal to                    =>   =

the total of p and 111    =>   p + 111

Put the equation together:

210 = p + 111

Usually, the variable is on the left side:

p + 111 = 210

To solve the equation is to isolate "p". This means to keep "p" on the left, and move everything else to the right side. When moving something, do the reverse operation to both sides of the equation.

p + 111 = 210            "111" should be on the left. It's opposite is -111.

p + 111 - 111 = 210 - 111                Simplify. "111" cancels out on the left.

p = 99                     Solved for "p"
