Answer 3

Let's solve the equation step by step:

3(x+1) + 7(x-3) = 10(x+2)

First, we'll simplify the expressions on both sides:

3x + 3 + 7x - 21 = 10x + 20

Combine like terms:

10x + 3x + 7x = 21 + 20

20x = 41

Divide both sides by 20:

x = 41/20

So, the solution to the equation is x = 41/20 or approximately x = 2.05.
