Question

Solve the system using elimination.
2x+3y=6
5x-y=-19

Answer 1

To eliminate one of the variables, make one of equations have equal variables just negative and positive. To do this, multiply the second equation by 3 to get -y to -3y, but you must multiply the whole equation.
15x-3y=-57
2x+3y=6

Answer 2

Add the equations together now! 15x+2x=17x
-57+6=-51
17x=-51
x=-3

Answer 3

Whoops, made a mistake.

Answer 4

First equal one of the variable in both of the equations
