Sagot :
Answer:
x=5
Step-by-step explanation:
To solve for x, you have to undo all the things that are being done to it
You undo an action by doing the opposite. For example, is 3 is added, then you subtract 3. If x is multiplied by 3, then you divide by 3.
In this case, 9x=45, what is being done to x? It is being multiplied by 9. What is the opposite of multiplication? Division. So you will divide it by 9 to cancel out the 9. You also have to divide the other side by 9, because what you do on one side, you must also do on the other.
9x=45
[tex]\frac{9x}{9}[/tex]=[tex]\frac{45}{9}[/tex]
x=5
The value of x in this equation is x = 5
This question is related to the first degree equation. To solve it, just: isolate x and divide both sides between them..
- 9x = 45
- x = 45 ÷ 9
- x = 5
Therefore, the answer will be x = 5
