Question

How do you solve the system of equations: y = 3x - 4 and 2x - y = 1?

Answer 1

I found:
`x=3`
`y=5`

Explanation:

You can substitute the value of `y` from the first equation into the second and solve for `x` as:
`2x-color(red)([3x-4])=1`
`2x-3x+4=1`
`-x=-3`
`x=3`
substitute back this value into the first equation to find `y`:
`y=3*(3)-4=5`

Answer 2

Refer to explanation

Explanation:

We have two equations

`y=3x-4` and `y=2x-1` Multiply the first with 2 and the second with three and substract them

`2y-3y=2*(3x-4)-3(2x-1)=>-y=-5=>y=5` and `x=3`
