Answer: 4
Step-by-step explanation:
We have to try getting x by itself to solve for it. Since we have two sides that are equal to each other, we can add, subtract, multiply, and divide anything on both sides to try to isolate x.
[tex]2(x+1)=10[/tex]
We can first divide the left side and the right side by 2. This would remove the 2 being multiplied on the outside.
[tex]\frac{2(x+1)}{2}=\frac{10}{2}\\x+1=10\div 2\\x+1=5[/tex]
Now, we have a + 1 on the left side that we need to remove to get x by itself. If we are adding something, we can remove that by subtracting the same thing. Hence, we can subtract 1 from both sides to remove the + 1.
[tex]x+1=5\\x+1-1=5-1\\x+0=4\\x=4[/tex]
After all that simplifying, we get that x equals 4.
