Solve the System of Equations

Solve the system by substitution: y = -7x - 8, y = -4x - 2.

Answer explanation

Solve the system by substitution: y = 6x - 24, -5x - 5y = 15.

Solve the system by substitution: -4x - 8y = 4, 6x + y = 5.

Solve the system by substitution: -8x - 5y = -7, -x - 2y = 6.

Solve the system by elimination: -5x + 9y = 16, 5x - 3y = 8.

Solve the system by elimination: -x - 2y = 4, -x - 4y = 2.

Solve the system by elimination: 6x - 9y = -24, -7x - 18y = -29.

Solve the system by elimination: 4x + 3y = -14, -6x - 4y = 20.
