| Solve the system: | 6x + 3y = 128x + 9y = 26. | |
| Solve the first equation (6x + 3y = 12) for y:Click here to see how.(In general, you just need to solve one of the equations for one of the variables.) | y = -2x + 4 | |
| Substitute this expression for y into the second equation: | 8x + 9(-2x + 4) = 26. | |
| Simplify: | -10x + 36 = 26. | |
| Solve for x:Click here to see how. | x= 1. | |
| Substitute this value for x into one of the original equations: | 6(1) + 3y = 12. | |
| Solve for y: | y = 2. | |
| Final Answer: | x = 1, y = 2. |
