Write the augmented matrix for the following system of equations. 3y – 3 = – 3x
0 = -5y + 2xC – 8z
0 = -X – 92 – 4

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

is there a question here?

step-by-step explanation:

2y+y=5

add 2y and y

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20
