Question

2x-(x+4)=9 how to solve the following equation ​

Answer 1

Step-by-step explanation:

2x-(x+4)=9

2x-x-4=9

x-4=9

x=13

Answer 2

so start with 2x-(x+4) then expand it like this, so go to - (x+4) and Distribute parentheses so it looks like - (x) - (4) then apply minus-plus rules so it looks like - x - 4, now you should have 2x - x - 4, add the similar elements like (2x - x = x) so you should have x - 4, after the expanding, you should have x - 4 = 9, so from there, add 4 to both sides and you should have 13 as your x, you're welcome :)
