3x+4<19
3x + 4 < 9
=3x<9-4
= 3x<5
= x<5/3
To solve the inequality 3x + 4 < 19, follow these steps:
Step 1: Subtract 4 from both sides of the inequality:
3x + 4 - 4 < 19 - 4
3x < 15
Step 2: Divide both sides of the inequality by 3 to isolate x:
(3x)/3 < 15/3
x < 5
Therefore, the solution to the inequality 3x + 4 < 19 is x < 5.
To solve the inequality 3x + 4 < 19, we need to isolate the variable x.
Step 1: Get rid of the constant term on the right side of the inequality by subtracting 4 from both sides:
3x + 4 - 4 < 19 - 4
3x < 15
Step 2: Divide both sides of the inequality by the coefficient 3 to isolate x:
(3x)/3 < 15/3
x < 5
So, the solution to the inequality 3x + 4 < 19 is x < 5.
