(t+20)=t+(t+10)

Solution for (t+20)=t+(t+10) equation:

(t+20)=t+(t+10)

We move all terms to the left:

(t+20)-(t+(t+10))=0

We get rid of parentheses

t-(t+(t+10))+20=0


We calculate terms in parentheses: -(t+(t+10)), so:

t+(t+10)

We get rid of parentheses

t+t+10

We add all the numbers together, and all the variables
