Solve 4x + 3 ≤ 19.
Solution
Problem
Solve 4x + 3 ≤ 19.
Subtract 3 from both sides: 4x ≤ 16
Divide both sides by 4: x ≤ 4
Because we divided by a positive number, the direction of the inequality does not change.
In interval notation, the solution is:(-∞, 4]
Divide both sides by 4: x ≤ 4
Because we divided by a positive number, the direction of the inequality does not change.
In interval notation, the solution is:(-∞, 4]
Result
x ≤ 4
