Exercise 37 Page 85

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

q=-117

Practice makes perfect
To solve the equation we have to isolate q on one side. By multiplying both sides of the equation by 3, we can eliminate the denominator and isolate q.
-39=q/3
(-39) * 3=q/3* 3
(-39) * 3=q
-117=q
q=-117
We can check the solution by substituting it into the equation and simplifying.
-39=q/3
-39? =-117/3
-39=-39
Since q=-117 satisfies the equation, we have found the correct solution.
