WebSolve for x, y, and z 1st Equation: 2x + 2y + 4z = 48 2nd Equation: 2x + 9y + 7z = 105 3rd Equation: x + 4y + z = 37 Subtract the 2nd Equation from the 1st Equation. This will eliminate the variable “x”. 2x + 2y + 4z = 48 - (2x + 9y + 7z = 105) ---------------------------- 0 - 7y - 3z = -57 -7y - 3z = -57 Solve for “z” in terms of y WebMay 25, 2024 · x + 2y − z = 3 2x − y + 2z = 6 x − 3y + 3z = 4 Solution The augmented matrix displays the coefficients of the variables, and an additional column for the constants.
