Igor estimates that he should save $20 per week to have enough money for college by the time he graduates high school. he finds out he will be able to graduate a year early. if he wants to start college right after graduation, what would need to happen to the amount he needs to save each week?

He needs to save more per week

Step-by-step explanation:

thats not how they wrote it on ttm but i think that is similar

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
