Solving Inequalities

100

solve for x (Remember to write the correct inequality symbol)

x + 4 ≥ 10

x ≥ 6

200

Solve for x:

2x > 11

x > 5

300

Solve for x:

2x + 5 ≥ –3

x ≥ –4

400

Solve for x:

–3x < 12

x > –4

500

Solve for x:

–5x > 2x + 21

x < –3

Solving Equations

100

Solve for y:

3y = 2y + 19

y = 19

200

Solve for x:

4x = 2x + 15

x = 7.5

300

3(x + 1) = 2(x – 2)

x = –7

400

Solve for x:

2x + 7 + 3x = 8 – 4x + 6 + 2x

x = 1

500

5(2x + 1) = x + 3 + x

x = -1/4
