Question

If four times a number is subtracted from 35, the result is ten more than three times the number. Which equation can be used to find the value of the number?\

Answer 1

The equation: 35 - 4x = 3x + 10

3.57

Explanation:

Let

x = the unknown number

35 - 4x = 3x + 10

Collect like terms

35 - 10 = 3x + 4x

25 = 7x

Divide both sides by 7

x = 25 / 7

= 3.57 approximately

The unknown number, x is approximately 3.57

The equation: 35 - 4x = 3x + 10

Answer 2

35 - 4x = 3x + 10

Explanation:

Given that :

Writing out the problem mathematically,

Let the number = x

35 - (4 * x) = (3 * x) + 10

35 - 4x = 3x + 10

-4x - 3x = 10 - 35

-7x = - 25

Hence x the equation which can be used to obtain the value of x is :

35 - 4x = 3x + 10
