Calculate a a
We begin by solving the two exercises inside of the parentheses:
We then divide each of the sections by 4:
In the fraction on the left side we simplify by 4 and in the fraction on the right side we divide by 4:
Remember that:
Lastly we divide both sections by 7:
4
Solve for X:
\( x - 3 + 5 = 8 - 2 \)
Simplifying first makes the problem much easier! (a + 3a) = 4a and (5 + 2) = 7, so you get the clean equation instead of a messy distribution.
Think of it like counting: a + 3a = 1a + 3a = 4a. Just add the coefficients (numbers in front) together. It's like saying 1 apple + 3 apples = 4 apples!
If substituting your answer doesn't work, go back and check your arithmetic. Make sure you simplified the parentheses correctly and divided both sides by the same number.
While you could distribute first, it's much more efficient to simplify parentheses first. This keeps the numbers smaller and reduces chances for calculation errors.
