6x+3+5+15x=21x+8

8+4x-3-3x=x+5

Answer 2

It looks like you have provided two mathematical expressions separated by a semicolon. Let's simplify each expression step by step:

1. Expression 1: 3(2x + 1) + 5(1 + 3x) Start by applying the distributive property (also known as the distributive law or the FOIL method): = 3 * 2x + 3 * 1 + 5 * 1 + 5 * 3x = 6x + 3 + 5 + 15x = 21x + 8

2. Expression 2: 4(2 + x) - 3(1 + x) Apply the distributive property again: = 4 * 2 + 4 * x - 3 * 1 - 3 * x = 8 + 4x - 3 - 3x = 1x + 5 = x + 5

So, the simplified expressions are:

1. 3(2x + 1) + 5(1 + 3x) simplifies to 21x + 8.
2. 4(2 + x) - 3(1 + x) simplifies to x + 5.
