Answer 1

Answer:

answer is option C

3+7=10

7-3=4

Answer 2

C.

Step-by-step explanation:

x + y = 10

x - y = 4

x = 4 + y

Okay, so now we substitute our third equation into equation 1. Then equation one becomes..

4 + y + y = 10

4 + 2y = 10 ┌(・。・)┘♪

Mk now we subtract 4 from both sides ofc.

2y = 10 - 4

2y = 6

Now divide by 2

y = 3

And now the last one-

substituting y = 3 into equation 3 to find the value of x!

(. ❛ ᴗ ❛.)

x = 4 + y, x = 4 + 3, x = 7

So, that's how I got this answer! (◕ᴗ◕✿)
