Step-by-step explanation:
"Each plan utilizes a combination of 2 strength-training sessions and 2 aerobic exercise sessions per week." because.
Let n be the number of aerobic and strength-training exercises per week.
Let x be the number of strength-training exercises per week on the beginner
15x + 20n = 90
Let y be the number of strength-training exercises for week on the advanced plan.
20y + 30n = 130
Multiply both sides by 1.5, to get:
22.5x + 30n = 135
Subtracting equation 2 from 3 we get:
22.5x - 20y = 5
It’s 65 not 55 because 113 times 5 is like 65 use a calculator
