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:
→ [tex] \frac{w}{3} -5=2[/tex]
Solving for w
Take 5 to the other side
[ When you see subtraction you do addition on the opposite side ]
→ [tex] \frac{w}{3}=2+5 [/tex]
[tex] \frac{w}{3}=7 [/tex]
Take 3 to the other side
[ When you see division you do multiplication on the opposite side ]
w = 3 x 7
w = 21
