I need help with this equation.

Question

y + 4y = 6 (1)

x = 9 - 4y (2)

Thanks for the help.

Answer 1

I'm not sure what kind of help you want.

1. 5y = 6

y = 6/5

2. If first equation is connected to second, substitute 6/5 for y and solve for x.

I hope this helps.

Answer 2

I think you have a typo. I'm guessing the first equation should have an x term, instead of two y's.

Answer 3

Thanks for the help. That should have been x + 4 instead of y + 4. Thanks for the help.
