Question

3x - 4y = 65x + 8y = -1

Answer 1

`\begin{gathered} 3x-4y=6 \\ 5x+8y=-1 \\ 3x=6+4y \\ x=2+(4)/(3)y \\ \\ 5(2+(4)/(3)y)+8y=-1 \\ 10+(20)/(3)y+8y=-1 \\ (20y+24y)/(3)=-11 \\ (44y)/(3)=-11 \\ 44y=-33 \\ y=(-33)/(44) \\ y=-(3)/(4) \\ \\ 3x-4(-(3)/(4))=6 \\ 3x+3=6 \\ 3x=3 \\ x=1 \end{gathered}`
