Q. Solve using elimination.\newline−7x−8y=−14-7x - 8y = -14\newline7x+4y=−147x + 4y = -14\newline(_,_)(\_, \_)
  1. Add Equations to Eliminate xx: Add the two equations to eliminate xx.\begin{align*} &-7x - 8y = -14 \ &+ 7x + 4y = -14 \ \hline &0x - 4y = -28 \end{align*}
  2. Solve for y: Solve for y.\newline−4y=−28-4y = -28\newliney=−28−4y = \frac{-28}{-4}\newliney=7y = 7
  3. Substitute to Find xx: Substitute y=7y = 7 into the second equation to find xx.7x+4(7)=−147x + 4(7) = -147x+28=−147x + 28 = -147x=−14−287x = -14 - 287x=−427x = -42x=−42/7x = -42 / 7x=−6x = -6
