7x over 8 (fraction = 21
I don't know how to solve this.
I don't like the presentation of your second line, but you last two lines are good
If you want to show all your steps, I prefer this:
7x/8 = 21
(7x/8)(8) = 21(8)
7x = 168
7x/7 = 168/7
x = 24
Another way to write this is 7x/8 = 21
multiply each side by 8
7x = 168
divide both sides by 7
x = 168/7 = 24
7x/8 = 21
Multiply both sides by 8.
7x = 168
x = 24
How does 7x = 168?
Oh, I get it now. Like this? :
7x / 8 = 21
x 8 x 8
7x/7 = 168/7
x = 24
Ok, thanks!
how u get 168
To solve the equation: 7x/8 = 21, you can follow these steps:
Step 1: Multiply both sides of the equation by 8 to eliminate the fraction:
(8 * 7x) / 8 = 21 * 8
This simplifies to:
7x = 168
Step 2: Divide both sides of the equation by 7 to isolate x and find its value:
(7x) / 7 = 168 / 7
This simplifies to:
x = 24
Therefore, the solution to the equation is x = 24.
