Question

You have $50 in your savings account and plan to deposit $10 each week. Your friend has $25 in her savings account and plans to also deposit $10 each week.

Write a system of linear equations that represents this situation.

Answer 1

There are $50 in saving and $10 are dposited each week. and friend has $25.

Ok so

y=10x+50

y=10x+25

The amount will never be equal

Explanation:

Answer 2

y=10x+50

y=10x+25

Use substitution

10x+50=10x+25

The 10x's eliminate

50=25

false equation

This means that there is no solution and they will never have the same amount of money in their bank account. If graphed, the two lines would never intersect.

Hope this helps! :)
