Answer 2

Solving the Expression 15a + 3 < 21 + 4a - 6

To solve the expression 15a + 3 < 21 + 4a - 6, we need to find the values of 'a' for which the inequality holds true.

Steps to Solve the Inequality

1. Combine Like Terms: Combine the like terms on both sides of the inequality. 2. Isolate the Variable: Move the terms involving 'a' to one side of the inequality and the constant terms to the other side. 3. Simplify: Simplify the inequality to find the range of values for 'a' that satisfy the inequality.

Step-by-Step Solution

1. Combine Like Terms: - The given inequality is 15a + 3 < 21 + 4a - 6. - Combining like terms, we get 15a - 4a + 3 < 21 - 6.

2. Isolate the Variable: - Subtract 4a from both sides: 11a + 3 < 21 - 6. - Simplifying, we get 11a + 3 < 15.

3. Simplify: - Subtract 3 from both sides: 11a < 12. - Finally, divide by 11: a < 12/11.

Conclusion

The values of 'a' for which the inequality 15a + 3 < 21 + 4a - 6 holds true are a < 12/11.
