You go to the market to buy vegetables. The person in front of you in line buy 2 avocados
and 1 cauliflower for $7.00. You buy 1 avocado
and 1 cauliflower for $4.50. Let x represent the
price per avocado. Let y represent the price per
cauliflower. Find the price of each vegetable.

2.5x+2y=price

Step-by-step explanation:

you buy one less avocado and the price drops $2.50. This means that each avocado is $2.50 and each cauliflower is $2.00.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
