The easiest way to solve this system of equations is by combination. You need to figure out the least common multiple of 10 and 8. This is 40. To get 40 from 10, you multiply by 4...so multiply the entire top equation by 4 to get . In order to get rid of the x in the combination, you need to get -40x in the second equation. To get this, multiply the entire equation by -5 to get . Now, you can add the two equations together to get.... Solve for y to get . To get x, plug this into either equation (I am going to use the top one). I get . Multilply to get . Move 20 to the right side of the equation to get . Divide to get , which reduces to .
