Question

solve this world problem.Half of a number,plus a fifth of two less than the number ,is 4 less than the number .What is the number​

Answer 1

Explanation:

let x be the number

1/2x + 1/5(x - 2) = x - 4

1/2x + 1/5x - 2/5 = x - 4....multiply by 10 to get rid of the fractions

5x + 2x - 4 = 10x - 40

7x - 4 = 10x - 40

-4 + 40 = 10x - 7x

36 = 3x

36/3 = x

12 = x <===
