Solve the system from the above question (same below) using Gaussian elimination and back-substitution.
2x + 3y + 2z = 16
6x + 7y + 7z = 12
2x - 3y + z = 8
When applying Gaussian elimination to the system below, three row operations are used to find an equivalent triangular system. The third row operation is: SUBTRACT (Please enter numeric values.) TIMES ROW FROM ROW 2x+3y+22= 6 6x+7y+7z = 12 2x-3y+2 = 8
