Step-by-step explanation:
[tex] \tt{2x + x + x + 2y \times 3y \times y}[/tex]
[tex] \text{Add \: the \: like \: terms : 2x \: + \: x \: + \: x}[/tex]
Like terms are those which have the same base. Like terms can be added or subtracted. Only coefficients of like terms can be added or subtracted.
⤑ [tex] \tt{4x + 2y \times 3y \times y}[/tex]
[tex] \text{Multiply : 2y, \:3y \: and \: y}[/tex]
⤑ [tex] \tt{4x + 6 {y}^{3}} [/tex]
Since , 4x and 6y³ are not like terms , they cannot be added. And we're done !
[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : 4x + 6 {y}^{3}}}}} [/tex]
Hope I helped ! ツ
Have a wonderful day / night ♡
