REORDER QUESTION

1 min • 1 pt

Reorder the following Solve by elimination -katex latex="-3x-8y=20"-katex -katex latex="-5x+y=19"-katex

To eliminate, multiply the top equation by 3

After plugging in y, you must solve the 2 step to get (-4,-4)

Take the y=-4 you got and plug in to get x

Now you can zero out the x's

You now have a one step, divide by -16
