Question

10 added to 3 times of a number gives 55.what is the number?​

Answer 1

Answer:

Let the unknown number be x

ATQ,

10 + 3x = 55

3x = 55 - 10

3x = 45

x = 15

Answer 2

Answer: The number is 15.

Step-by-step explanation:

Let the unknown number be x

then according to the question,

10+3x=55

Subtracting 10 from both sides,

3x=55-10

3x=45

Dividing 3 on both sides,

x=45/3

x=15

So the unknown number x is 15.

Verifying the result,

10 + 3(15) = 55

10 + 45 = 55

55 = 55

Hence proved, the unknown number is 55 since left hand side = right hand side of the equation. Always follow the BODMAS rule while solving Maths equations. First solve brackets, then division then multiplication, then addition and then subtraction.
