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

x =$\frac{7}{16}$ y = - $\frac{7}{8}$
6x - 5y = 7 first equation 4x - 6y = 7 second equation multiply by -2 the first equation and by 3 the second equation -12x + 10y = -14 12x - 18 y = 21 ______________ -8y = 7 add the equations to eleminate x y = - $\frac{7}{8}$ divide both sides by -8 let y in the firest equation 6x - 5y = 7 6x - 5 (- $\frac{7}{8}$) = 7 6x + $\frac{35}{8}$ = 7 6x = $\frac{56}{8}$ - $\frac{35}{8}$ 6x = $\frac{21}{8}$ x = $\frac{21}{48}$ x = $\frac{7}{16}$
