Question

Explain, in complete sentences, which method you would use to solve the following system of equations and why you chose that method. Show your work and provide the solution to the system.

5x + 3y = –7
4x – 2y = –10

Answer 1

elimination

Answer 2

I would use elimination method (because I always use this). Multiplying equation 1 by 4 and equation 2 by 5, then subtracting eq 2 from eq 1. thus getting22y= 22, y=1. then substituting y=1 in eq 1

Answer 3

multiply top equation by 2 multiply bottom by 3

cancel y variable out to solve x

Answer 4

5x + 3y = –7 (multiply by 2)
4x – 2y = –10 (multiply by 3)

10x + 6y = -14
12x - 6y = -30

add together
cancelling out the y variable

giving you

22x = -44

22x / 22 = -44 / 22

x = -2

Answer 5

now use this to work out y

Answer 6

can you do the rest?

Answer 7

yes thank you so much<3
