x=1

200

Find the value of x: 

2(4-2x)=-2(x+5) 

x = 9

300

3(x-4) = -12 + 3x

0 = 0

Infinitely many solutions

400

Find the value of y: 

5x + 2y = 12

12-5x / 2 = y OR 6 - 5x/2 = y

500

100

Use elimination to solve this equation: 

5x + y = 9 

10x + 2y = 3

0 = -15

No solution

200

Identify the x and y intercepts: 4x + 2y = -8

x= -2

y = -4

300

-1 < 9 + x < 17

-10 < x < 8

400

Use the points to make an equation: (3,-2)  (0,-5)

y=mx+b

100

Find the value of x: 

2(x+5) = 3x + 5

x = 5

200

Find the value of x

-5x + 1 + 2x = x - 4x

1 = 0 

No solution

300

Use elimination to solve this equation: 

x - y = 11

2x + y = 19

x = 10, y = -1, (10,-1), 11 = 11

400

2(x -30) = 4(x - 10)

x = -10

500

Use the points to make an equation: (4,3)  (0,-5)

y = mx + b

y = 2x - 5

4x - 5 > 11 or 9 - 8x ≥ 25

x > 4 or x ≤ -2

500

Use substitution to solve the equation: 

y = x + 5

y = -2x -4

y = 2, x = -3, (-3, 2)
