Alg. 1- Solving Equations

-4x + 1 = 21

• x=120
• x=5
• x=30
• x=-5

What is the first step to solve this equation:

- 3x -11 = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

Solve for x:

2x - 3 + 4x = 27

• x = 12

• x = 4

• x = 5

• x = 15

Solve for b:
 3(b - 4) = -3

• b = 3
• b = -3
• b = 5
• b = -5

Solve for x:

2x -1(3+4x) = 11

• x = -4

• x = 7/3

• x = -7

• x = -17/8

Solve for a:

-8(-4+a) + 3(2a+1) = -19

• a = 27

• a = -27

• a = 3.86

• a = 1.67

Solve the equation.

x-27= -(27-x)

• x= -1
