Question

Use substitution to solve the following system of equations. Show all of your work. Write the solution as an ordered pair.

Answer 1

`\left \{ {{x=2} \atop {y=2}} \right.`

Explanation:

Substitute the second equation into the first one:

`4x+(2x-2)=10\\6x-2=10\\6x=12\\x=2`

Substitute
`x=2` into the second equation:

`y=2* 2-2\\y=4-2\\y=2`

`\therefore \left \{ {{x=2} \atop {y=2}} \right.`
