Answer:


Step-by-step explanation:

x + y = 25 ...........................(1)

{4x + 2y  =64} / 2    divide the equation by 2

2x + y = 32 ........................(3)

Step Two

subtract (1) from (3)

2x + y = 32

x   + y = 25

x = 7

Therefore from equation 1 we get x + y =  25

but x = 7

7 + y = 25       Subtract 7 from both sides.

y = 25 - 7

y = 18

Check

4*x + 2*y =  64

4*7 + 2*18 =? 64

28 + 36 = ? 64

64 = 64

The checks out to be the right answer.

Answer:

A

Step-by-step explanation:

To sovle this we must combine the numbers togther and the variables togther.

We have:

8c+6-3c-2

Lets take out the c's and combine them:

8c -3c

=

5c

Now lets take out the numbers:

6-2

=

4

Now lets put these back together and we get the expression:

5c+4

This looks like A.

Hope this helps! :D
