Answer:

1. x = 2.6

2. 7x + 1

Step-by-step explanation:

Given:

4.75x = 12.35

Find x

4.75x = 12.35

Divide both sides by the coefficient of x, that is 4.75

4.75x / 4.75 = 12.35 / 4.75

x = 2.6

Check

4.75x = 12.35

4.75(2.6) = 12.35

12.35 = 12.35

Given:

3x + 2 + 4x - 1

Combine like terms

3x + 4x + 2 - 1

7x + 1
