Yasha thought of a number. He multiplied his number by 7, then subtracted 2. Finally, he divided the result by 4. His final result was 10. What was Yasha’s original number?

[x * 7  -  2] / 4 = 10, solve for x

Cross multiply

[x* 7 - 2] =40

Add 2 to both sides

x * 7 = 42

Divide both sides by 7

x =42 / 7

x = 6
