Alg. 1-Solving Multi Step Equations 8/26

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

2x + 3(5x - 7) = 47

• 1

• 2

• 3

• 4

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

-(n - 8) = -2

• 6
• 10
• -10
• -6

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

Solve the equation:
3(x - 1) = 2x + 9

• x = 12
• no solution
• x = 10
• x = 6

Describe the solution set:
2(x + 5) = 2x + 5

• one solution
• no solution
• infinitely many solutions
• two solutions

Which step cannot be performed first when solving the equation
5 - 2(x - 7) = x + 1 + 3x

• Distributing -2 to (x - 7)
• Combining x and 3x
• Subtracting 1 from both sides
• 5 - 2

Solve the equation:
4 - 6x - 2= -2(3x-1)

• no solution
• infinitely many solutions
• x = ⅓
• x = 4

Which of the equations has no solution?

• 2x + 1 = 5x - 3
• 2(x - 7) = 2x-14
• 3(2x+1) = 6x+1
• 15x - 30 = 0
