Exercise 34 Page 85

How can you eliminate the denominator on the left-hand side?

x=84

Practice makes perfect
To solve the equation we have to isolate m on one side. By multiplying both sides of the equation by 7, we can eliminate the denominator and isolate m.
m/7=12
m/7*7=12*7
m=12*7
m=84
Therefore, m=84 is the solution to the equation. To check that we have the correct solution, we can substitute m=84 into the original equation and simplify.
m/7=12
84/7? =12
12=12
Since the left-hand side and right-hand side are equal, m=84 is the correct solution.
