this one shouldn't be upside down

Answer 5

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

Answer 6

yes you get t=25

Answer 7

yup, that's right

Answer 8

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

Answer 9

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 = ... ?

Answer 10

typo .. i mean 50 + 10 + 3x =180

Answer 11

x=40

Answer 12

correct again

Answer 13

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

so, y = ...

Answer 14

y=30

Answer 15

good finishing :)

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

t = ...

Answer 20

t=4

Answer 21

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