Question

Find the solution of the system of equations.
2.x + 4y = -14
– 2y = 9

Answer 1

x = 4, y = -9/2 (-4.5)

Explanation:

Using the second equation, we can divide both sides by -2 and get

y = 9/-2

y = -9/2

Then, we plug this y value into the first equation and get:

x + 4(-9/2) = -14

Simplify:

x - 18 = -14

x = 4
