Multiply by 3: To solve the inequality (3x)≤7, we need to isolate x. We can do this by multiplying both sides of the inequality by 3, which is the denominator of the fraction on the left side.Calculation: 3×(3x)≤3×7
Cancel out 3: After multiplying both sides by 3, the 3 on the left side cancels out with the denominator of the fraction, leaving us with x on the left side.Calculation: x≤3×7
Multiply by 7: Now we multiply 3 by 7 to find the value that x must be less than or equal to.Calculation: x≤21
Final Solution: The inequality x≤21 means that x can be any real number less than or equal to 21. This is the solution set for the inequality.
