Balanced Equations
Date
Equations are balanced when both sides are equal (=). They are not
balanced when the two sides are not equal (≠).
Think about holding a T-shirt in one hand and something heavier, like
a pair of boots, in the other hand. You can tell that they are not the
same weight.

T-shirt ≠ boots
If the two sides have the same totals, they are equal. They are equal
even if the numbers on each side are different:
2 × 8 = 4 × 4
(16) = (16)
Sometimes you have to figure out what number to add or subtract
from one side to make the two sides equal, or balanced.
(1 + 2) × __ = 5 × 6
First, simplify.

3 × __ = 30
You need to multiply 3 by 10 to balance the equation.
(1 + 2) × 10 = 5 × 6
Write = or ≠.
1. 1 + 5 5 + 1 3. 5 + 2 × 4 28
2. 5 × 3 10 + 5 4. 18 ÷ 6 18 ÷ 3
Explain what you need to do to balance each equation. The first
problem has been done for you.
5. 4 × (3 + 6) = 6 ×
Multiply the right side by 6.
6. + 3 = 5 × 2
7. (6 + 2) × 8 = 4 × 2 ×
