Which of the following algebraic expressions is not simplified?

B.

Step-by-step explanation:

we will verify each options

option-A:

we have

we can see that x and 1 are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-B:

we have

we can see that 2x and x are same type of terms

so, they are  like terms

so, we can  combine or simplify it

So, this expression is not in simplest form

this is TRUE

option-C:

we have

we can see that x^2 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-D:

we have

we can see that 5x^3 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man
