Linear Equations Review!

One and Two Step Equations

100

What is the goal to SOLVING EQUATIONS??

ISOLATE the Variable ( get the variable by itself on one side of the equal sign)

200

a+4=8

a=4

300

(3/5)x = -6

x = -10

400

-3z - 7 = 11

z = -6

500

-6 = 3 - b/7

b = 63

Distributive Property

100

2(x+1) = 4

x = 1

200

-3(y+3) = 3

y = -4

300

-20 = 4(2a+3)

a = -4

400

-28 = -5(3b+2)

b = 6/5

500

-6 = -(-10-4x)

x = -4

Combining Like Terms

100

3(w+2) +w = 6

w = 0

200

8a +2 - 6 - 2a = 3+5

a = 2

300

2(3-h)-6 = -5h

h = 0

400

6n +5 +2n -3 = 3n +7 -6 +4n 

n = -1

500

-2(5x-1) - 4 = 22 -7x +8(3x-1)

x = -16/27

Solving ANY LINEAR EQUATION

100

(x/2) = (3/4)x - 5

x = 20

200

3/8(2-4x) = -5/4 + x/2

x=1

300

(a-2)/4 = (3a+1)/3 +2

a = 34/9

400

3/4 (2x-3) = 5/6 (-2x-4x) 

x= 7/58

500

-2 +1/5(-4a+6) = 1/10 (3+2a)

a = -11/10
