Answer:
p + 111 = 210
p = 99
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.
