▸Solution: x = 29/17, y = 26/17
- Substituting back: the values satisfy both original equations exactly.
- The determinant of the coefficient matrix is -17, which is non-zero, confirming a unique intersection point.
- The elimination method works by scaling equations so that adding or subtracting them cancels one variable, leaving a single equation in one unknown.
Next stepAlways verify your answer by substituting x and y back into both original equations to confirm the left-hand side equals the right-hand side.
