Question

using elimination cancellation solve the problem for x and y 5x-6y=48
2x=5y=-3

Answer 1

\[5x-6y=48[1]\]
\[2x+5y=-3[2]\]
\[[1] \times 2\]
\[2(5x-6y)=2(48)\]
\[10x-12y=96[3]\]
\[[2] \times 5\]
\[5(2x+5y)=5(-3)\]
\[10x+25y=-15[4]\]
\[[3]-[4]\]
\[(10x-12y)-(10x+25y)=(96)-(-15)\]
\[-12y-25y=96--15\]
\[-37y=96+15\]
\[-37y=111\]
\[y=-3\]

Answer 2

Find x by replacing y with -3 in one of the equations,
