Answer:
x=3 15/16 hours together
Step-by-step explanation:
the painter paints 1/7 of the house in 1 hour
the assistant paints 1/9 of the house in 1 hour
x=# of hours it takes them together to paint the house
(1/7)x+(1/9)x=1 (job finished)
multiply both sides by the LCM which is 63
63(1/7)x+63(1/9)x=63(1)
9x+7x=63
16x=63
x=63/16
x=3 15/16 hours together
12(x-3)+18=4(3x-3)
Distribute.
12x-36+18=12x-12
Add like terms.
12x-18=12x-12
Add 12 to both sides.
12x-6=12x
Subtract 12x from both sides.
-6=0
