Hey there! Hello!
For this problem, you need to use the distributive property to expand the variables into one equation. In my attachment, I'll show you how to do this.
If you need to then factor out the equation back into two binomials, you could either do it the way I show you, or you could just factor out the GFC's of both binomials, 2 and 4, to get 8. Either way, it's good to know how to do these steps. If the "re-factoring" step isn't necessary for your question, the second line down in the lower portion of my work.
I hope this helped you out! Feel free to ask me any additional questions if you have any. :-)

Answer:
x = 1
Step-by-step explanation:
When there is a "-" (minus) sign in front of parenthesis, we distribute the sign inside. Let's do this with "-(x+1)". So we will have:
Now, we follow rules of algebra. We take variables to one side and numbers to another side (remember to change signs with changing sides). Shown below:
Now, we add like terms in left side. Such as:
ax + bx = (a+b)x
Thus, we have:
Now, we add right side and divide and get a value for x:
The value of x is 1
Looks like you did most of it.
The next step would be setting them equal to 105, like the problem suggests.
Then we can plug back in to find the numbers.
The three numbers are .
Hope this helps.
