Solution

Step 1 :\( \begin{cases} -8x+3y=3 \\ 13x-3y=-18 \end{cases} \)

Step 2 :Add the two equations: \( -8x+3y+13x-3y=3-18 \)

Step 3 :\( x=\frac{3-18}{-8+13} \)

Step 4 :\( x=-\frac{15}{5} \)

Step 5 :\( x=-3 \)

Step 6 :Plug \(x\) value into the first equation: \( -8(-3)+3y=3 \)

Step 7 :\( 24+3y=3 \)

Step 8 :\( 3y=-21 \)

Step 9 :\( y=-7 \)
