Question

Find the solution of the system of equations. x-3y= -13
2x+15y=16

Answer 1

Answer:
`x=-7, y=2`

Explanation:

Multiplying the first equation by 2 gives
`2x-6y=-26`

Subtracting this from the second equation yields
`21y=42 \longrightarrow y=2`

Substituting this back into the first equation gives that
`x=-7`

`\therefore x=-7, y=2`
