7k divided by 3=21
Can you please show me the work? I know that k=9 but I don't know how to show the work.
7k divided by 3=21
Multiply both sides of the equation by 3.
7k = 63
Divide both sides by 7
k = 9
k= 9
-6k+7k
Of course! I can help you with that.
To find the value of k in the equation 7k divided by 3 equals 21, we can use algebraic steps. Here's how you can show the work:
Step 1: Write the equation: 7k/3 = 21
Step 2: Multiply both sides of the equation by 3 to get rid of the denominator (3):
3 * (7k/3) = 3 * 21
Step 3: Simplify the left side of the equation:
(3/1) * (7k/3) = 21
The 3s in the numerator and denominator will cancel out, leaving you with:
7k = 21
Step 4: Divide both sides of the equation by 7 to isolate the variable k:
(7k)/7 = 21/7
The 7s on the left side will cancel out, and you'll be left with:
k = 3
So, the value of k in the equation 7k divided by 3 equals 21 is k = 3.
