Question

How do you solve by substitution `2x=3y` and `x=3y-3`?

Answer 1

`x = 3`
`y = 2`

Explanation:

First, substitute `3y` in the second equation with `2x` (this is given to us in the first equation), and solve for x:

`x = 2x -3`
`x= 3`

Insert x's value back into first equation, and solve for y:

`2 * 3 = 3*y`
`y = 2`

Solution is: `x = 3, y = 2`
