Question

How do you solve the system of linear equations: `y = 4x - 3` and `y = - 3x - 3`?

Answer 1

I found:
`x=-3`
`y=0`

Explanation:

You can try substitute the first equation into the second for `y` so that you get:
`color(red)(4x-3)=-3x-3` solve for `x`:
`7x=0`
`x=0/7=0`
substitute this into the first equation:
`y=4*color(red)(0)-3=-3`
