Solve for X:
113−128x+31x=21+42−2422x
To solve this problem, let's break down the equation step-by-step:
Start with the original equation:
113−128x+31x=21+42−2422x
Step 1: Simplify the fractions where possible.
- 128=32: Simplifying 128x gives us:−32x
- 42=21
- 2422 simplifies to 1211: So, −2422x becomes −1211x
The equation now looks like this:
113−32x+31x=21+21−1211x
Step 2: Combine like terms.
- −32x+31x=−31x
- 21+21=1
So, the equation simplifies to:
113−31x=1−1211x
Step 3: Move all terms involving x to one side:
Add 31x to both sides:
113=1−1211x+31x
Combine the terms with x:
- −1211x+31x=−1211x+124x=−127x
Thus, the equation is:
113=1−127x
Step 4: Isolate x:
Subtract 1 from both sides:
113−1=−127x
Convert −1 to a fraction with a common denominator to the left side:113−1111=113−11=−118
Now the equation is:
−118=−127x
Multiply both sides by the reciprocal of −127 to solve for x:
x=−118⋅−712=11⋅78⋅12=7796
Thus, the solution to the equation is 7796.
