−47(−x)+2x−5(x+3)=−x
x=?
To solve the given linear equation −47(−x)+2x−5(x+3)=−x, follow these steps:
- Step 1: Distribute the coefficients across the terms within parentheses:
The term −47(−x) becomes 47x because −47×−x=47x.
The term −5(x+3) can be expanded to −5x−15.
- Step 2: Simplify the equation by combining like terms:
The equation becomes 47x+2x−5x−15=−x.
- Step 3: Combine the x-terms on the left side:
Combine: 47x+2x−5x.
Converting all terms to a common denominator, 2x=48x and −5x=4−20x. Thus,
47x+48x−420x=4−5x.
- Step 4: The equation simplifies to:
4−5x−15=−x.
- Step 5: Isolate the x terms onto one side:
Add x to both sides, treating −x as 4−4x:
4−5x+x−15=0, which simplifies to 4−1x−15=0.
- Step 6: Isolate x:
Add 15 to both sides:
4−1x=15.
- Step 7: Solve for x:
Multiply both sides by −4 to isolate x:
x=15×−4.
Thus, x=−60.
Therefore, the solution to the equation is x=−60.
