Solve for X:
To solve , we first simplify both sides:
Left side:
Right side:
Now the equation is .
Subtract 2 from both sides:
So, .
1
\( x+7=14 \)
\( x=\text{?} \)
You could, but it's much easier to simplify first! When you have 5 + x - 3 = 2 + 1, combining like terms gives you 2 + x = 3, which is much cleaner to work with.
Look for constant numbers (numbers without variables). On the left side: 5 and -3 combine to make 2. On the right side: 2 and 1 combine to make 3. Leave x alone until after simplifying!
Yes, always! Simplifying makes the equation easier to solve and helps you avoid mistakes. It's like cleaning your workspace before starting a project.
Check that you've combined all the like terms you can. Constants go with constants, and variables stay separate. If you see 2 + x = 3, you know you're ready to solve!
Always substitute your answer back into the original equation! If x = 1, then 5 + 1 - 3 should equal 2 + 1. Both sides equal 3, so x = 1 is correct!
