Question

10 subtracted from half of a number gives 15.what is the number?​

Answer 1

Answer:

ATQ,

$\frac{x}{2} - 10 = 15\\\frac{x-20}{2} = 15\\x- 20 = 30\\x= 30 + 20\\x=50$

Answer 2

Answer: The number is 50.

Step-by-step explanation:

Let the unknown number be x.

According to the question, $\frac{x}{2} -10 =15$

Adding 10 on both the sides of the equation,

x/2 = 15+10

x/2 =25

By cross multiplication method,

x=25x2

x=50

Hence the unknown number is 50.

Verifying the result, 25-10=15

15=15

Hence proved that the unknown number is 50 since the left hand side of the equation is equal to the right hand side of the equation. Always follow BODMAS rule in solving mathematics equations. First solve brackets then divide then multiplication is solved. Then addition and then subtract.
