the value of x in the equation.

9x= 45

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
