Question

Solve the system of equations.
2x + 3y = 4
y = 5x - 27

Answer 1

x = 5, y = -2.

or as an ordered pair it's (5, -2).

Explanation:

2x + 3y = 4

y = 5x - 27

-5x + y = -27 Multiply this by - 3:

15x - 3y = 81 Add this equation to the first equation:

17x = 85

x = 5

Plug this into the second equation:

y = 5(5) - 27

y = -2.
