3x+7y=5x+2y−3x+7y=5x+2yminus, 3, x, plus, 7, y, equals, 5, x, plus, 2, y

complete the missing value in the solution to the equation.

(-5,(−5,left parenthesis, minus, 5, comma

))

The complete missing value in the solution to the equation is (-5,-8).

Step-by-step explanation:

Consider the provided equation.

We need to find the missing value of the coordinate; (-5__)

To find the missing value substitute x = -5 in above equation.

Hence, the missing value is -8.

Thus, the complete missing value in the solution to the equation is (-5,-8).

4 + 5 7/9= 9 7/9

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
