When solving a system of equations by elimination, there are multiple correct ways you can start. Which of the following is *NOT* a correct first step for the
given system? *
5x – 3y = -7
3x + 15y = -1
-25x + 15y = 35
3x + 15y = -1
15x - 9y = -21
15x + 75y = -5
25x – 15y = -35
3x + 15y = -1
5x - 15y = -7
3x + 15y = -1

Below.

Step-by-step explanation:

Its the bottom right option.

They have only multiplied the - 3y by 5 in the first equation whereas they should have multiplied all the terms by 5.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
