It’s c because if you move six times to the right you get 2 and just add the half and you get 2 1/2
5x - 9 ≤ 21
5x ≤ 21 + 9
5x ≤ 30
x ≤ 30 ÷ 5
x ≤ 6
I believe it is A
Because his initial starting point is 12 and then 1.5x to increase and reach his goal of 26
2x - 4 = 8
2x = 8 + 4
2x = 12
x = 6
so he answer is e. 6
