12k + 15 = 35 +2k

• k = 2

• k = 4

• k = -2

• k = -4

6x + 5 = 10 + 5x

• x = -5

• x = 6

• x = 4

• x = 5

Solve for x:
5x - 14 = 8x + 4

• x = 6
• x = -6
• x = -18/13
• x = 10/3

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
