Question

What is the solution to the system of equations?
2x+y=-3
x-2y=-4

Answer 1

Re-arrange the 2nd equation:

x - 2y = -4

Add 2y to both sides:

x = 2y - 4

Plug in '2y - 4' for 'x' in the first equation:

2(2y - 4) + y = -3

Distribute 2:

4y - 8 + y = -3

5y - 8 = -3

Add 8 to both sides, what's -3 + 8?
