Question

Determine the number of solutions,

y = -x-4
12y + 48 = 8x

Answer 1

one solution

Explanation:

The ratios of x-coefficient to y-coefficient for these equations are -1 and 2/3. These values are different, so the lines have one point of intersection.

There is one solution.

__

The solution is (x, y) = (0, -4).
