Let d = # digital cameras
Let m = # manual cameras
d + m = 240 equation 1
(d-82) = 3(m-26) equation 2
d - 82 = 3m - 78
d - 3m = 82 - 78
d - 3m = 16 equation 2 simplified
We have two equations with 2 unknowns:
d + m = 240
d - 3m = 16 subtract equation 1 from equation 2
---------------
-4m = -224
m = -224/-4
m = 56
d + m = 240
d = 240-m
d = 240-56
d = 184
He started with 184 digital cameras and 56 manual cameras
Answer:
AD
Step-by-step explanation:
To solve it you have to distribute (multiply) the 4 to the x and the 2.Then you would have to subtract 8 by both sides and which it would cancel on the left side, then after you divide 4 by both sides and then u get you answer.
I didn't mean to post the answer and can't figure out how to take it down. Somebody report it so it does go down and the question can be later answered. Thank you
