Answer: 4x + 1
Step-by-step explanation: Like terms are numbers that have the same variable. We will also combine the numbers that do not have a variable.
3x-4+x+5
Step 1: Put the like terms and numbers together. (3x+x) + (-4+5)
3x + x = 4x and -4 + 5 = 1
Step 2: Solve inside the parentheses. 4x + 1
So the simplified answer is 4x + 1
