Solve for x:

12k + 15 = 35 +2k

• k = 2

• k = 4

• k = -2

• k = -4

is 7 a solution to the equation
3x+8-x=5x-4

• yes

Jacob solved the following equation using the steps shown.

Step 1 5x + 9 = 2x - 3

Step 2 3x + 9 = -3

Step 3 3x = -12

Step 4 x = -4

What operation did he perform to get from Step 1 to Step 2?

• Subtracted 2x from both sides of the equation

• Subtracted 9 from both sides of the equation

• Multiplied both sides of the equation by 3

• Added -3 to both sides of the equation

What is the error?

• Adding 2x to 3x

• Subtracting 5 from both sides

• Adding 2x to -2x

• Dividing by 5 on both sides

Where is the first mistake?

• Distribution of the 5

• Distribution of the 10

• subtracting 60x from both sides

• dividing by -50

Where is the first mistake?

• Subtracting 3 on both sides

• Distributing the 9

• Subtracting 9x on both sides

• Inequality error

Which statement best describes the first step to the equation?

• Add 3 to both sides

• Add 11 to both sides

• Get the variables on one side

• Add 2 to both sides

What is the first step in solving a multi-step equation with variables on both sides?

• Distribute

• Combine like terms on each side of the = sign

• Move the variable

• Solve for the variable
