Please answer the question

Answer 1

First you need to multiply both sides with 15 :
15*4/3=(x+10)/15*15
5*4=x+10
20=x+10
x=20-10
x=10

Answer 2

`\boxed{C) \ 10}`

Explanation:

You need to solve for x.

`(4)/(3)=(x+10)/(15)`

An equation can be thought of as a balance scale, so we must do the same operation on both sides in order to maintain equality.

Multiply by 15 on both sides:

`(4)/(3) (15) =(x+10)/(15) (15)\\\\(4(15))/(3) =\frac{(x+10)\\ot{15}}{\\ot{15}}\\\\20=x+10`

Finally, subtract 10 on both sides.

`20-10=x+10-10\\10=x \implies x=10`

Therefore, the correct answer is option C.
