Step 1: Simplify the left side of the inequality.
3x−41(21)>41−x
Multiply the fractions on the left side:
3x−81>41−x
Step 2: Gather all terms containing x on one side and constant terms on the other side.
Add x to both sides of the inequality:
3x+x−81>41
4x−81>41
Add 81 to both sides of the inequality:
4x>41+81
Step 3: Combine the constant terms on the right side.
Find a common denominator for 41 and 81, which is 8.
41=4×21×2=82
Now add the fractions:
4x>82+81
4x>83
Step 4: Solve for x.
Divide both sides by 4:
x>8×43
x>323
Step 5: Express the solution as an interval.
The inequality x>323 means that x can be any value strictly greater than 323. In interval notation, this is written as:
(323,∞)
