$\large\underline{\rm{PROBLEM}:}$

A boy has 4x-5 red marbles,3x+8 yellow marbles and 6+5x green marbles.How many marbles does he have in all?

$\sf\underline{CHOICES:}$

$\tt\color{red}{\overline{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad}}$

$\large\underline{\rm{ANSWER}:}$

$\tt\color{red}{\overline{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad}}$

$\large\underline{\rm{GIVEN}:}$

$\tt\color{red}{\overline{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad}}$

$\large\underline{\rm{SOLUTION}:}$

➢ To find how many marbles does he have in all we need to, add all marbles does he have at all.

$\ \: \: \: \small\sf{5x \: + \: 6} \\ + \: \: \small\sf{4x \: + \: - 5} \\ \: \: \: \small\sf\underline{3x \: + \: 8} \\ \: \: \: \: \small\sf\color{green}{12x \: + \: 9}$

⟹ Therefore, the total marbles that he has are $\small\sf{12x \: + \: 9}$

$\tt\color{red}{\overline{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad}}$
