A 800 seat multiplex is divided into 3 theatres. There are 270 seats in Theatre 1, and there are 150 more seats in Theatre 2 than in Theatre 3. How many seats are in Theatre 2?

uuhhh is it .... Let x = number of seats in Theatre 3 T1 = Theatre 1 = 270 seats T2 = Theatre 2 = 150 + x T1 + T2 + T3 = 800 seats 270 + (150 + x) + x = 800 420 + 2x = 800 x = 190 If there are x = 190 seats in theatre 3 and then that means Theatre 2 has 150 + 190 = 340 seats ??

Let x = number of seats in Theatre 3

T1 = Theatre 1 = 270 seats

T2 = Theatre 2 = 150 + x

T1 + T2 + T3 = 800 seats

270 + (150 + x) + x = 800

420 + 2x = 800

x = 190

If there are x = 190 seats in theatre 3 and then that means

Theatre 2 has

150 + 190 = 340 seats ??

i remember doing something like this before ..
