Solve for x
9x - 7 = 4x + 13
i need help with this i’m so confused in this topic

x = 4

Step-by-step explanation:

ur welcome

x=4

Step-by-step explanation:

First, you need to take both of the x to one side of the equation. To do that, subtract 4x from both sides of the equation. you will get 9x-7-4x=4x+13-4x. The 4xs on the right hand side of the equation will cancel out. So you will be left with an equation that looks like this: 9x-7-4x=13. Now, on the left hand side of the equation you can rearrange the numbers to look like this. 9x-4x-7=13. Do 9x-4x to get 5x and then add back your -7 and the =13. Now, your equation will look like this. 5x-7=13. Now, you need to get rid of the 7 on the left hand side of the equation in order to isolate the variable (which is x here). The easiest way to do this would be to add 7 to both sides (in order to keep the equation balanced, whatever you do on one side of the equation has to also be done on the other side.) of the equation so the +7 and -7 could cancel each other out. You would have 5x-7+7=13+7. Now, cancel out the 7s on the left hand side of the equation. You would be left with 5x=13+7. Add the 13 and the 7 on the right hand side of the equation to get 20. You would now have the equation 5x=20. Finally, you need to isolate the x, right? To do that, just divide both sides of the equation by 5. you would get 5x/5=20/5. And your final answer after simplifying should be x=4. Hope this helps!
