Question

What is the solution of the system? Use elimination.

3x – 4y = –24
x + y = –1
A. (–4, 3)
B. (0, 6)
C. (3, 4)
D. (4, 3)

Answer 1

To use elimination we first must choose which variable to eliminate. Which one do hou choose, the x or the y?

Answer 2

*hou is you

Answer 3

Either one may be chosen. The one chosen will be algebraically manipulated so that the coefficient will of both will be equal.

Answer 4

@chicagochica5 , do you want to learn how to solve this problem?

Answer 5

Is the answer A?

Answer 6

It may be, but I would need to work it out, but I need the variable you wish to eliminate (x or y) to do that.

Answer 7

Does it matter what one you eliminate?

Answer 8

No, but you need to eliminate one, to solve the other!

Answer 9

I would pick the variable that has opposite signs. That way simple addition will eliminate it. Which variable in those two equations has opposite signs?

Answer 10

Have you used the elimination method before?
