Question

solve using the addition method
6x+3y=0
8x+5y=8

Answer 1

You just add each together. 6x+8x=14x, 3y+5y=8y, 0+8=8

So you end up with 14x+8y=8

Did you need it in slope-intercept form?

Answer 2

If you do, you subtract the x value over to get 8y=-14x+8

Then divide both sides by 8 to isolate y. y=-14/8x+1

Simplified it is y=-7/4x+1
