Translate the sentence into an equation. The difference of a number divided by 3 and 5 is equal to 2 . Use the variable w for th
Whitepunk [10]
Hey there :)

Let us translate each one separately
{ Using w for unknown }

The difference of a number divided by 3 and 5 is 2
'is' is the key-word, meaning you apply the = sign
Difference is subtraction

 → a number divided by 3 - 5 = 2

This is your equation:
 → \frac{w}{3} -5=2
 
Solving for w
Take 5 to the other side
[ When you see subtraction you do addition on the opposite side ]
 → \frac{w}{3}=2+5 
\frac{w}{3}=7

Take 3 to the other side
[ When you see division you do multiplication on the opposite side ]
w = 3 x 7
w = 21
