4x - 2y = 22
Start by adding 2y to both sides to cancel out the -2y
4x = 22 + 2y
Now you can divide by 4
x = 22/4 + 2y/4
Reduce all the fractions to get your answer, which is
{(5,2), (8,9), (2,7),(-5,3)(4,0),(3,11)}<br>

Answer:

Step-by-step explanation:
h(x) + k(x) = x² + 1 + x - 2 = x² + x - 1
(h + k)(2) = 2² + 2 - 1 = 4 + 2 - 1 = 5
h(x) - k(x) = x² + 1 - (x - 2) = x² + 1 - x + 2 = x² -x + 3
(h - k)(3) = 3² - 3 + 3 = 9 - 3 + 3 = 9
h(2) = 2² + 1 = 4 + 1 = 5
k(3) = 3 - 2 = 1
3h(2) + 2k(3) = (3 × 5) + (2 × 1) = 15 + 2 = 17
