Solving by Collecting Constants
To solve , begin by identifying which side of the equation holds the variable term. Because appears only on the left, designate the left as the variable side and the right as the constant side.
Step 1 — Remove the misplaced constant from the variable side: The constant is on the variable side, so subtract from both sides using the Subtraction Property of Equality:
Now all variable terms are on the left and only a constant remains on the right.
Step 2 — Isolate the variable using the Division Property of Equality: Because is multiplied by the coefficient , divide both sides by :
Step 3 — Check by substitution: Replace with in the original equation:
Because both sides are equal, is confirmed as the correct solution. This example shows that when the variable appears on only one side of the equation, any constants on that same side must first be moved to the opposite side before the coefficient can be divided away.
