Use a related equation that has the variable on one side. Then simplify the other side.
p + 6 = 18
To find a related equation that has the variable on one side, we can subtract 6 from both sides of the equation p + 6 = 18.
Doing so, we have:
(p + 6) - 6 = 18 - 6
This simplifies to:
p = 12
Therefore, the related equation with the variable on one side is p = 12.
