Answer:
x = 1.56
Step-by-step explanation:
so what you have to do is isolate the variable by dividing each side by factors that don't contain the variable.
1st week - Lost 3 pounds = +3
2nd week - Gained 1 pound = -1
3+13 = + 22
So 22+3 = 25 25-1 = 24
So Tina lost 24 pounds in 13 weeks.
Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.
