Answer: x = -2

Step-by-Step Explanation:

Since the two expressions both equal y, you can set them equal to each other.

2x-1 = 3x+1

Subtract 2x from both sides.

-1 = x+1

Subtract 1 from both sides.

-2 = x

The first option is cheaper if that’s what you’re asking.
It’s cheaper because it has a smaller slope so overall will have a lower price than the other option.

A 15% tax is to be applied to a $120 pair of shoes. Find the total price.
postnew [5]

Total cost of item = $138

Explanation:

The tax percentage = 15%

cost of item = $120

sales tax = cost of item × The tax percentage

sales tax = 120 × 15%

=120 × 0.15

sales tax = $18

Total cost of item = initial cost of item + sales tax

Total cost of item = 120 + 18

Total cost of item = $138
