Solving Two-Step and Multistep Equations

Is there a mistake on the equation solved? If so where was the mistake made?

• This equation is solved correctly.

• The mistake was made on the distributive property step on the left side.

• The mistake was made on combining like terms on the left side.

• The mistake was made on moving the variable to the left side and constant to the right side.

• The mistake was made on the distributive property step on the right side.

Solve the equations:

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

• 4

• 3

• 2

• 1

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:
4 - 6x - 2= -2(3x-1)

• no solution

• infinitely many solutions

• x = ⅓

• x = 4

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

Which equation has a solution of x = 1

• 2x + 1 = 12

• 5x - 2 = 3

• x + 1 = x - 1

• 5 - x = 6

Finish the sentence: When solving multistep equations....

• I am Very Confident.

• I still need need some practice.

• I have no clue what's going on.

Which of the equations has no solution?

• 2x + 1 = 5x - 3

• 2(x - 7) = 2x-14

• 3(2x+1) = 6x+1

• 15x - 30 = 0
