  • Dividing

In some situations, you have to divide both sides of the equation by the same number. When is that? It’s in the situation where there are only x’s (blocks) on one side and there is more than one circle on the other side.

Example:

lever9

Let \( \scriptsize \boxed {?} = x \\ \scriptsize \; and \; \LARGE \circ \scriptsize (circle) = 1\\ \scriptsize \therefore x \: + \: x = 8 \\ \scriptsize \rightarrow 2x = 8 \)

Note: Because there are 8 circles and 2 boxes

If you take away half of the things on the left side and similarly half of the things on the right side, the balance will stay balanced.

lever10

Therefore we have:

lever11

Therefore x = 4

Note: Because there are 4 circles and 1 box

Solving the equation without a scale model;
