Simplify:

3(2n - 4) -5(3 + 2n)

6n - 12 - 15 -10n

6n - 10n - 12 - 15

-4n -27

Solve for y:

5y + 24 = -36

5y + 24 = -36

5y = -60

y = -12

500

solve for s:

2(9s + 3) - 4s = 34

2(9s + 3) - 4s = 34

18s + 6 - 4s = 34

14s + 6 = 34 

14s = 28 

s = 2 

Is

Simplify:

-2x(x - 3) + 4x² + 5 + 2x 

-2x² + 6x + 4x² + 5 + 2x

2x² + 8x + 5 

400

solve for x:

x/5 - 13 = -84

x/5 - 13 = - 84

x/5 = -71

x = -355

500

Solve for x: 

7x - 20 = 2x + 25

7x - 20 = 2x + 25

7x = 2x + 45 

5x = 45

x = 9

Always

100

The difference of a number and five

n - 5 

200

Evaluate when x = 2 and y = -4 

7x + 2y 

7(2) + 2(-4) 

14 + (-8)

300

Simplify: 

5x - 2(4x + 8) - 11

5x - 8x - 16 - 11

-3x - 27

400

solve for w:

17 - w = -13

17 - w = -13 

-w = -30

w = 30 

500

solve for x:

7(x - 9) = 3(x - 2)

7(x - 9) = 3(x - 2)

7x - 63 = 3x - 6

7x  = 3x + 57

4x = 57 

x = 57/4 or 14 1/4 or 14.25

With

100

The sum of a number squared and two

n² + 2 

200

Evaluate when x = -3; y = 2, and z = 10 

x + y² - 2z 

-3 + 2² - 2(10)

-3 + 4 - 20

1 - 20

-19

300

Simplify:

5 - (2x - 3) + 12x 

5 - 2x + 3 + 12x 

10x + 8 

400

solve for w:

4(w - 7) = 8 

4w - 28 = 8 

4w = 36

w = 9 

500

solve for x:

5(x - 4) + 4x = 9x - 20

5(x - 4) + 4x = 9x - 20

5x - 20 + 4x = 9x - 20 

9x - 20 = 9x - 20 

9x = 9x + 0 

9x = 9x 

Identity! 

You

100

The product of eight and a number

8n

200

Simplify:

4(b + 9)

4b + 36

300

Simplify: 

6(x + 3) - (x - 7)

6x + 18 - x + 7

5x + 25 

400

solve for n:

2n - 4(n - 3) = 26

2n - 4n + 12 = 26 

-2n + 12 = 26

-2n = 14 

n = -7

500

solve for b:

82b - 9b + 7 = 73b + 19

82b - 9b + 7 = 73b + 19

73b + 7 = 73b + 19

73b = 73b + 12
