Solving Equations with variables on both sides of the equation

2x = x + 3

• 6
• 3
• 2
• x

30 + 6x = 11x

• 3
• 5
• 6
• 30

10x + 9 = 4x - 9

• 0
• 3
• -3
• -18

8x - 8 = -4x + 16

• 8

• 16

• 24

• 2

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

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

Solve the equation
4x - 5x + 9 =5x - 9

• x = -3
• x = 9
• x = 3
• x = -9

1) 6r + 7 = 13 + 7r
