Solve using the addition and mulitplication method principles. 4+9x<13. Is this right? 4-4 +9x<13-4
9x/9> 9/9
x>1?
No, you should not have changed the direction of the <, since you divided by a positive number.
almost, the < sign only changes to a > sign when both sides are multiplied by a minus.
so the answer is x<1
Hope that helps
To solve the inequality 4 + 9x < 13 using the addition and multiplication principles, let's break it down step by step:
Step 1: Subtract 4 from both sides of the inequality:
4 - 4 + 9x < 13 - 4
Simplifying, we get: 9x < 9
Step 2: Now divide both sides of the inequality by 9 to isolate the variable x:
(9x)/9 > 9/9
This simplifies to: x > 1
So, you are correct. The solution to the inequality 4 + 9x < 13 is x > 1.
