Answer

The solution to the system of equations is \(\boxed{x = 0}\) and \(\boxed{y = 1}\)

Steps

Step 1 :Given the system of equations: \(-7x - 6y = -6\) and \(-5x + 9y = 9\)

Step 2 :First, multiply the first equation by 5 and the second equation by 7 to make the coefficients of x the same in both equations. This gives us: \(-35x - 30y = -30\) and \(-35x + 63y = 63\)

Step 3 :Subtract the second equation from the first to eliminate x: \(93y = 93\)

Step 4 :Solve for y: \(y = 1\)

Step 5 :Substitute y = 1 into the first equation: \(-7x - 6(1) = -6\)

Step 6 :Solve for x: \(x = 0\)

Step 7 :The solution to the system of equations is \(\boxed{x = 0}\) and \(\boxed{y = 1}\)
