0

Step-by-step explanation:

Let's solve your system by substitution.

y=−3x+5;y=−3x−6

Step: Solvey=−3x+5for y:

y=−3x+5

Step: Substitute−3x+5foryiny=−3x−6:

y=−3x−6

−3x+5=−3x−6

−3x+5+3x=−3x−6+3x(Add 3x to both sides)

5=−6

5+−5=−6+−5(Add -5 to both sides)

0=−11

No solutions.

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.
