Answer 3

It seems like you have two mathematical expressions that need to be solved for the variable x. Let's solve them step by step:

1. x + 1 < 2 To solve this inequality for x, we need to isolate x on one side of the inequality sign. Follow these steps:

Subtract 1 from both sides: x + 1 - 1 < 2 - 1 x < 1

So the solution for this inequality is x < 1.

2. 2x - 5 = 3 To solve this equation for x, we need to isolate x on one side of the equation sign. Follow these steps:

Add 5 to both sides: 2x - 5 + 5 = 3 + 5 2x = 8

Now, to find the value of x, divide both sides by 2: x = 8 / 2 x = 4

So the solution for this equation is x = 4.

In summary:

1. For the inequality x + 1 < 2, the solution is x < 1.
2. For the equation 2x - 5 = 3, the solution is x = 4.
