Verified answer

Step-by-step explanation:

We can solve for x in the first inequality:

2x - 1 ≤ 7

2x ≤ 8

x ≤ 4

So x must be less than or equal to 4.

To find the largest possible value of x+3, we can simply plug in the maximum value of x:

x + 3 ≤ 4 + 3 = 7

Therefore, the largest number that x+3 can have is 7.

2x - 1+(1) ≤ 7+(1)

2x ≤ 8

2x/2 ≤ 8/2

x = 4

x + 3

= 4 + 3

= 7
