Solve for X

100

3x = 24

x = 8

200

5x + 16 = 76

x = 12

300

3x - 12 + 4x = -47

x = -5

400

2(x + 9) + 7x - 15 = 7.5

x = 1/2

500

3(y + 7) - 2(y - 12) = 30

y = -15

One Solution, No Solution and Infinite Solution

100

3x = 3x

Infinite Solution

200

4x + 5 = 4x - 5

No Solution

300

3(x + 11) - 12 + 5x = -3

x = -3

400

4x + 8 + 2 = 4(x - 3)

No Solution

500

3(x - 5) - x + 7 = 2(x + 4)

Infinite Solutions

Distributing with Fractions

100

1/2(4x + 8) = 12

x = 4

200

1/3(9 - 24x) = 2(2x + 3)

x = -1/4

300

3/4(12 + 4x) -10 = 5x + 4

x = -2/5

400

3/5(15 - 25x) - 6 = 33

x = -2

500

1/4(2x - 12) + 8 = -2/3(9 + 3x)

x = -4 2/5

Solve for y when x = 3

100

y = x + 5   

y = 8

200

y = 2x - 16

y = -10

300

y = 3x - 15 

y = -6

400

6 + y = 2x + 7

y = 7

500

4x + y = -3 + 2x

y = -9
