(t-50)+(t-20)=(t+40)

Solution for (t-50)+(t-20)=(t+40) equation:

(t-50)+(t-20)=(t+40)

We move all terms to the left:

(t-50)+(t-20)-((t+40))=0

We get rid of parentheses

t+t-((t+40))-50-20=0


We calculate terms in parentheses: -((t+40)), so:

(t+40)

We get rid of parentheses

t+40

Back to the equation:

-(t+40)


We add all the numbers together, and all the variables

2t-(t+40)-70=0

We get rid of parentheses

2t-t-40-70=0

We add all the numbers together, and all the variables

t-110=0
