12x+2y=112
6x+y=56
6x=56-y

x=(56-y)/6
y=(56-6x)

2y=-12x+112                12x=-2y+112
y=-6x+56                         x=-1/6y+28/3

To find the value of x or y, you must know what the other is. But the equation can be changed to y=-6x+56 or x=-1/6y +28/3

Answer along with how you got the answer <br> 3/8 + 1/8 + 2/8 = ?
zzz [600]

Answer:

6/8 simplified form 3/4

Step-by-step explanation:

Given: 3/8 + 1/8 + 2/8

Here we have to find the sum of the fractions.

All the fractions are like fractions.

So we can add the numerators and keep the denominator as it is. (We should not add the denominator)

Therefore,

3/8 + 1/8 + 2/8 = (3 + 1 + 2)/8

= 6/8

We can simplify this fraction by dividing both the numerator and the denominator by 2.

= 6/8

= 3/4

Hope this is will help you to understand the concept.

Thank you.

Joel had a coin collection. He had two hundred coins,
OverLord2011 [107]

Answer:

Joel's coin collection had 120 dimes and 80 quarters.

Step-by-step explanation:

Given that Joel had a coin collection of two hundred coins, which were dimes and quarters, and the total value was worth $32, to determine how many coins of each type he had, the following equations must be performed:

0.25 - 0.10 = 0.15

200 x 0.10 = 20

32 - 20 = 12

12 / 0.15 = 80

200 - 80 = 120

(80 x 0.25) + (120 x 0.1) = X

20 + 12 = X

32 = X

Therefore, Joel's coin collection had 120 dimes and 80 quarters.
