56.) first, solve for t for the equation : 3t - 15 = 2t + 10 can u solve this ?

OpenStudy (nerdy_3000):

yes you get t=25

alright then what do I do with the 4y and 3x in which it is very confusing?? I don't understand it

OpenStudy (raden):

now, solve for x for the equation : 2t+10+3x = 180 we have t = 25 before, so put into equation above 2(25) + 10 + 3x = 180 50 + 10 + 3x + 180 60 + 3x = 180 now, x = ... ?

x=40

correct again

OpenStudy (raden):

now to get y, take the equation of : 4y = 3x (put x=40, first) 4y = 3(40) 4y = 120 so, y = ...

ok, solv for t first 5t - 17 = 2t - 5 t = ...

OpenStudy (nerdy_3000):

t=4

OpenStudy (raden):

yes, correct then solve for g, take the equation of : g = t + 2 just put t = 4, ofcource g = 4+2 = 6
