Answer:
x ≤ 4 OR x < 2.25
Explanation:
a. Given 5x − 19 ≤ 1
5x ≤ 1 + 19
5x ≤ 20
Now, make x the subject of the formula, we have:
x ≤ 20/5
x ≤ 4
Therefore, given 5x − 19 ≤ 1, the solution is x ≤ 4
OR
b. Given − 4x + 3 < − 6
− 4x < − 6 − 3
− 4x < − 9
Now, make x the subject of the formula, we have:
x < −9/−4
x < 2.25
Therefore, given − 4x + 3 < − 6, the solution is x < 2.25.
Conclusion:
The solution to solve for x in 5x−19≤1 OR −4x+3<−6 is x ≤ 4 OR x < 2.25
