Answer:

7x-8=48

x=8

Explanation:

7x-8=48

first, to remove the -8 from the side with the 7x, we need to add 8 to the -8. since we added 8 to the -8, we need to add 8 to the 48, which should look like this:

7x-8=48

+8 +8

Now the equation should look like this:

7x=56

Now, we need to divide 7 on both sides so we can have x by itself. It would look like this:

7x/7=56/7

Now the equation would look like this:

x=8

Hope this helped!!!

1- first add the 8 to 48.
You are trying to undo the equation to get to the x, so you would do the reverse of subtraction and add.
That would equal 56. (7x= 56)
2- Now you divide 56 by 7. Like above, we are trying to undo the equation. 7 times x equals 7x, so we divide to undo it. 56/7 equals 8. So, x=8.
