7x/8 = 21
i am kind of confused on this
I did 21 divided by 8 = 2.625
but how do you know how to get it?
To solve the equation 7x/8 = 21, you can follow these steps:
Step 1: Start by multiplying both sides of the equation by 8 to eliminate the fraction:
(8)(7x/8) = (8)(21)
7x = 168
Step 2: Divide both sides of the equation by 7 to isolate the variable x:
(7x)/7 = 168/7
x = 24
Therefore, the solution to the equation 7x/8 = 21 is x = 24.
7x/8 = 21
7x = 168
x = 24
or,
7(x/8) = 21
x/8 = 3
x = 24
If you divided 21 by 8, you were just guessing.
