Substitution
1. 2x + 3y = 5
2. x - 5y = 9
| 1. 2x + 3y = 5 2. x - 5y = 9 |
First, you would begin by solving equation 2 for x. |
| x = 9 + 5y | Then you would plug that equation into equation 1. |
| 2(9 + 5y) + 3y = 5 | You would then solve that equation for y. |
| y = -1 | you would then plug that answer into your equation from step 2 |
| x = 9 + (-5)(-1) | Solve the equation |
| x = 14 | And then you would have your answer |
| (14, -1) | the end |
