Question

Solve the system of equations. - 3x + 2y = 56 - 5 - 2y = 24

Answer 1

Awnser

y=13

Step-by-step explanation:

-3x+2y=56

-5x-2y=24

so first we want to get rid of one variable, in this example we dont need to multiply because the y's cancel out

so we have

-8x=80

x=-10

now plug in x into an original equation

-3(-10)+2y=56

2y=26

y=13

hope that helps

Answer 2

Answer:

x = -85/3, y = -29/2

Step-by-step explanation:

-3x + 2y = 56 +

-5 - 2y = 24   =

-3x - 5 = 80

-3x = 85

x = -85/3

Plugging this into the original equation, we find out that y = -29/2.
