Answer 2

Let's solve each equation step by step:

1. 2x + 1 = 3 Subtract 1 from both sides: 2x = 3 - 1 2x = 2 Divide both sides by 2: x = 2 / 2 x = 1

2. 14 - x = 16 Subtract 14 from both sides: -x = 16 - 14 -x = 2 Multiply both sides by -1 (to isolate x on one side): x = -2

3. 5x = 15 Divide both sides by 5: x = 15 / 5 x = 3

4. 46 ÷ x = 8 Divide both sides by 8: 46 ÷ x = 8 x = 46 / 8 x ≈ 5.75 (rounded to two decimal places)

5. 144 ÷ (5x - 3) - 2 = 10 Add 2 to both sides: 144 ÷ (5x - 3) = 10 + 2 144 ÷ (5x - 3) = 12 Multiply both sides by (5x - 3): 144 = 12(5x - 3) Divide both sides by 12: 12(5x - 3) = 144 5x - 3 = 12 Add 3 to both sides: 5x = 12 + 3 5x = 15 Divide both sides by 5: x = 15 / 5 x = 3

So, the solutions to the equations are as follows:

1. x = 1
2. x = -2
3. x = 3
4. x ≈ 5.75 (rounded to two decimal places)
5. x = 3
