Question

Exercise 6
Solve the following equation.

Answer

m=4

Hint

Start with expanding the expressions on both sides.

Solution

We need to find the value of m for which the two sides evaluate to the same number. We start with expanding the expressions on both sides of the equality.
3(3m2)=2(3m+3)
9m6=6m+6
Next we use inverse operations to isolate m.
9m6=6m+6
9m6m6=6
9m6m=12
(96)m=12
3m=12
m=4
Hence, the value that makes the equality true is m=4.
