Solve for X:
To solve for in the equation , we will follow these steps:
Step 1: Combine the coefficients of by finding a common denominator.
- The denominators are 3, 4, 5, and 2. The least common multiple (LCM) of these is 60.
- Rewrite each term with a denominator of 60:
, , , .
Step 2: Combine the fractions:
- Combine to get:
Step 3: Set up the equation and solve for :
- The equation becomes .
- Multiply both sides by to isolate :
.
Therefore, .
\( x+7=14 \)
\( x=\text{?} \)
List the multiples of each number until you find the smallest one they all share: 60 is the first number divisible by 3, 4, 5, and 2.
All the terms are combined on the left side of the equation. You must add or subtract the coefficients of x first, then solve for x in one step.
Be extra careful with signs! The term is subtracted, so when combining:
You could work with decimal equivalents, but fractions give exact answers. Decimals might introduce rounding errors and make verification harder.
To solve , multiply both sides by :
