Question

Solve this system of linear equations.

4x+5y=-24
16x-2y=-8

Answer 1

do what we have been doing, eliminate and put it into the other equation..

Answer 2

Okay, but idk how you made the equation, it confuses me :(

Answer 3

Okay here:
4x+5y=-24
Slove for y in terms of x

Answer 4

equations can be manipulated to bend to our will; we can multiply them by any number and they retain their inherent value/ proportions:

Lets choose a number that will benefit us; lets see what happens when we multiply the top equation here by -4

4x+5y=-24 ; *-4
16x-2y=-8


-16x-20y=96
16x- 2y=-8 ; now add the results together
--------------
0x -22y =88 ; now we solve for y

Answer 5

x=-1
y =-4
