Chapter 2 Study Guide Review

Lesson 2-1 & 2-2

100

Twice the difference of a number and 4 equals 3

2(w-4)=3

200

Five times the sum of a number and 4 is 8

5(x+4)=8

300

Solve for y:

6+y=3

y=-3

400

Solve for x:

11=8+x

x=3

500

7y-4y=15

y=5

500

Solve for y:

3(2y+8)=60

y=6

Lesson 2-4

100

Solve for x:

2x+9=8x+21

x=-2

200

Solve for x:

7(x+9)=-9x-17

x=-5

300

Solve for v:

3(v-2)=9v+7-2(-2v-1)

v= -3/2

400
