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

x = 4 y = - $\frac{1}{5}$
6x - 5y = 25 first equation 18x - 15y = 75 multiply by 3 4x + 15y = 13 second equation ____________________________ 22x = 88 add the equations to eleminate y x = 4 divide by 22 let x = 4 in first equation $6\times4$ - 5y = 25 24 - 5y = 25 - 5y = 1 subtract 24 from both sides y = - $\frac{1}{5}$
