## Algebra: A Combined Approach (4th Edition)

x = 2 y =- $\frac{1}{2}$
3x - 2y = 7 first equation 6x - 4y = 14 multiply by 2 both sides 5x + 4y = 8 second equation ________________ 11x = 22 add the equations to eliminate y x = 2 divide both sides by 11 let x = 2 in first equation $3\times2$ - 2y = 7 6 - 2y = 7 - 2y = 1 subtract 6 from both sides y = - $\frac{1}{2}$
