let the unknown number = x x/5-2=8 x/5=10 (add 2 to both sides of the equation) x=50 (multiply by 5 to both sides of the equation)
x5-2=8 ⬇️ (8+2)➗5 =x
(8+2) ➡️10⤵️ 10➗5 ➡️2⤵️ 2=x✅
The unknown number is 50. We find this by setting up the equation 5 x − 2 = 8 and solving for x . After isolating x and solving, we conclude that x = 50 .
