question 5 of 28
solve for y.
-3y + 11 = -8y + 51
simplify your answer as much as possible.

Explanation:

Question 4

Step1: Define total cost equation

Let $m$ = number of minutes. Total bill: $7 + 0.07m = 17.43$

Step2: Isolate the variable term

Subtract 7 from both sides:
$0.07m = 17.43 - 7$
$0.07m = 10.43$

Step3: Solve for m

Divide by 0.07:
$m = \frac{10.43}{0.07}$

Question 5

Step1: Collect y terms on left

Add $8y$ to both sides:
$-3y + 8y + 11 = 51$
$5y + 11 = 51$

Step2: Isolate the variable term

Subtract 11 from both sides:
$5y = 51 - 11$
$5y = 40$

Step3: Solve for y

Divide by 5:
$y = \frac{40}{5}$

Answer:

Question 4: 149 minutes
Question 5: $y = 8$
