Equations

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 $$8.$$
