Question

The sum of 5 times a number and 12 less than 2 times a number is the same as 61.

Write an equation and solve to determine the value of the unknown number.

Answer 1

Step-by-step explanation:The sum of three times a number and 2 less than 4 times that same number is 61.

To find:

The equation and the value of the unknown number.

Solution:

Let the number be x.

Since the sum of three times a number and 2 less than 4 times that same number is 61, thus the equation will be:

3x + (4x-2) = 61

On solving, we get:

7x - 2 = 61

7x = 63

x = 9

Thus, the equation will be 3x + (4x-2) = 61 and the value of the unknown number will be 9.
