Solving Equations and Inequalities

ONE STEP

100

x - 3 = 5

x = 8

200

x + 4 = 3

x = -1

300

x/4 = 5

x = 20

400

6x - 3x = 30

x = 10

500

-2/3x = 12

x= -18

TWO STEP

100

2x + 5 = 15

x = 5

200

-69 = 7x - 6

x = -9

300

36 - x = -36

x = 72

400

-10 = - 4x - 10

x = 0 

500

-13(4 + 2a) = 208

a = -10

MULTI-STEP

100

3x + 2( x - 5) = 25

x = 7

200

3( x + 7) = 6 ( x + 2)

m = 3

300

x + 2x + 3 + 3 = 3 (x + 2)

6 = 6

 Infinite Solution

400

2( x + 5) = 2x + 5

10 = 5

 No solution

500

1/2(8x +10)= 2/3( 9x - 6)

x = 9/2

INEQUALITY

100

2x - 4x < -2

x > 1

200

x - 15 > -4 ( -6 + 3x)

x>3

300

7 < - ( -x -3) + 2

x > 2

400

-8x + 2x - 16 < -5x + 7x

x > -2

500

2/5(5x - 10) - (x+3)< -5 + 2(x+5)

x>-12

SOLVE FOR Y

100

5x-4y=16

y=5/4x-4

200

x+2y=-20

y=-1/2x-10

300

y + 1= -(x-1)

y= -x

400

y - 5 = 1/2(x + 12)

Y=1/2X + 11

500

y + 9 = 11/5( x - 2)

y=11/5x-67/5
