Answer:

[-3,5)

Step-by-step explanation:

Compound inequality

We are required to solve:

2x - 3 < 7

And :

5 - x = 8

The solution is the conjunction (AND) of the individual solutions because both conditions must be met.

From the first inequality we have:

2x < 7 + 3

2x < 10

x < 5

From the second inequality we get:

- x = 8 - 5

- x = 3

Multiplying by -1 and flipping the sign:

x = -3

Thus the solution is the set of numbers that lie in the interval [-3,5)
