What is unknown?

Statements of the given equations.

Reasoning:

To solve this question, look at the equation carefully and decide the variable and numbers. Then write the suitable statement using the variables and numbers.

Steps:

  (i) The sum of \(p\) and \(4\) is \(15.\)

 (ii) 7 subtracted from \(m\) is \(3.\)

(iii) Two times \(m\) is \(7.\)

(iv) One-fifth of \(m\) is \(3.\)

 (v) Three-fifth of \(m\) is \(6.\)

 (vi) When \(4\) is added to three times of a number \(p,\) it gives \(25.\)

(vii) When \(2\) is subtracted from four times of a number \(p\), gives \(18.\)

(viii) When \(2\) is added to half of \(p\) gives \(8.\)
