Question
Exercise 6
Solve the following equation.
3(3m−2)=2(3m+3)
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(3m−2)=2(3m+3) 9m−6=6m+6
Next we use inverse operations to isolate
m.
9m−6=6m+6 9m−6m−6=6 (9−6)m=12
Hence, the value that makes the equality true is
m=4.
