Solve the system by graphing. It is REQUIRED to check your solution. Show work for this problem on your work page. y = x -1

y = -2x -4

Let's solve for x.

y=x−1

Step 1: Flip the equation.

x−1=y

Step 2: Add 1 to both sides.

x−1+1=y+1

x=y+1

x=y+1

---------------------------------

Let's solve for x.

y=−2x−4

Step 1: Flip the equation.

−2x−4=y

Step 2: Add 4 to both sides.

−2x−4+4=y+4

−2x=y+4

Step 3: Divide both sides by -2.

−2x

−2

=

y+4

−2

x=

−1

2

y−2

x=

−1

2

y−2

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
