Answer:

Then the solution is (4, 6).

Explanation:

Let's use the substitution method:

First multiply the second equation by 4, obtaining 4y = -2x + 32.

Now substitute (-2x + 32) for 4y in the first equation:

3x + (-2x + 32) = 36, or

3x - 2x + 32 = 36. or

x = 4.

If x = 4, then the second equation yields y = (-1/2)(4) + 8, or

y = -2 + 8, or y = 6

Then the solution is (4, 6).

Check, using the first equation:

Does 3(4) + 4(6) = 36? Does 12 + 24 = 36? YES
