Answer:
Step-by-step explanation:
It is hard to read but (5x - 2) + (7x - 9) = AC also 5x - 2 = 7x - 9
5x - 2 = 7x - 9 subtract 5x from both sides then add 9 to both sides
5x - 5x - 2 + 9 = 7x - 5x - 9 + 9
-2 + 9 = 7x - 5x
7 = 2x
3.5 = x
5x - 2 = 7x - 9
3 ≠ -2 when x = 1
8 ≠ 5 when x = 2
13 ≠ 12 when x = 3
15.5 = 15.5 when x = 3.5
18 ≠ 19 when x = 4
