3x + 4 = 19

• x = 23

• x = 7.67

• x = 5

• x = 4

4(-x + 4) = 12

• x = - 1

• x = 1

• x = - 2

• x = 2

18 = 3(3x − 6)

• x = 8

• x = - 4

• x = - 8

• x = 4

6x + 7 = 13 + 7x

• x = - 6

• x = - 12

• x = - 1

• x = 5

4x - 6 = 14

• x = 12

• x = 4

• x = 20

4x − 40 = 7(−2x + 2)

• x = 7

• x = 3

• x = 5

• x = - 6

7x − 3 = 3 + 6x

• x = 6

• x = 0

• x = 3

• x = - 3

3x + 2(4x - 4) = 3

• 4
• 3
• 2
• 1

3a + 9 + 4a = 2

• -1
• 1
• no solution
• -7

What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add 4 to both sides
• Add the 2a and a 
• Distribute 4 to a and -5
• Distribute -4 to a and -5
