Solve for X:
First, simplify both sides of the equation:
Left side:
Right side:
Now the equation is:
Subtract 2 from both sides to isolate :
Simplifying gives:
4
\( x+7=14 \)
\( x=\text{?} \)
It doesn't matter which side you start with! The key is to simplify both sides completely before trying to isolate x. This makes the equation much cleaner to work with.
When you skip simplifying, you might accidentally combine wrong terms or make calculation errors. Working with directly is much more confusing than !
Think of it as starting with -3 and adding 5: -3 + 5 = +2. You can also use a number line: start at -3, move 5 steps right to reach +2.
You could solve it, but it's much harder! You'd need to add 3 to both sides, then subtract 5, making multiple steps instead of one clean step.
Substitute x = 4 into the original equation: 4 - 3 + 5 should equal 8 - 2. Both sides give 6, so your answer is right!
