Question

begin{array}{l}3 x+2 y=-18  2 x+9 y=-12end{array}

Accepted Answer

Step:1 ：Multiply the first equation by 2 and the second equation by 3: (begin{cases} 6x + 4y = -36  6x + 27y = -36 end{cases})Step:2 ：Subtract the second equation from the first equation to eliminate x: (-23y = 0)Step:3 ：Solve for y: (y = 0)Step:4 ：Substitute the value of y back into one of the original equations to find the value of x: (3x + 2(0) = -18)Step:5 ：Solve for x: (x = -6)Step:6 ：(boxed{x = -6, y = 0})
