Answer 1

Let the number be x

ATQ

`\\ \sf\longmapsto 7x-4x-2=58`

`\\ \sf\longmapsto 3x-2=58`

`\\ \sf\longmapsto 3x=58+2`

`\\ \sf\longmapsto 3x=60`

`\\ \sf\longmapsto x=(60)/(3)`

`\\ \sf\longmapsto x=20`

Answer 2

The number is 20

Explanation:

7 times a certain number :

Let the unknown number be x

`7 * x`

is less four times that same number -2 is 58 :

7x - 4x -2 = 58

Collect like terms

7x-4x = 58+2

3x = 60

3x/3 = 60/3

x = 20
