5x + 6 = 21
-6 -6
-------------------
5x = 21
(divide 5 on both sides to get rid of the number to get the variable by itself on both sides which makes X = 4.2

How do you divide 3.4÷12.92
Travka [436]
Well 3.4 goes into the house and 12.92 is outside of it. 3.4 is a smaller number so you'd add zeros to get the 12.92 into 3.4. As you add zeros you'd take the decimals out and move them to the right two times. But u actually move the decimal first than adding zeros. Step 1: Take out the decimals. Step 2: Add the zeros. Step 3: Hope this helped.
