Answer:
15 equations
Step-by-step explanation:
Let
Number of equations in the homework = x
There is only a one-word problem
y = amount of time used to solve the word problem
She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total,
Total = 3x + y
52 = 3x + 7
Subtract 7 from both sides
52 - 7 = 3x + 7 - 7
45 = 3x
Divide both sides by 3
x = 45 / 3
= 15
x = 15 equations
Therefore, she solved 15 equations
