What is the first step to solve this equation? 5x + 6 = 10 + 3x + 4x

• Add 4x to both sides of the equation

• Combine the terms 3x and 4x on the same side of the equation

• Add 5x and 6 to get 11x

• Combine the terms 5x and 3x and 4x to get 12x

What is the next step to solve this equation?
3x + 6 = 10 + 7x

• Add 6 to both sides of the equation

• Add 10 to both sides of the equation

• Add 7x to both sides of the equation

• Subtract 7x from both sides of the equation

Find the error in the problem.

• Should have added 19 to -1.

• Should have subtracted 3k instead of adding 3k to both sides.

• Should have gotten k = 20 since two negatives make a positve.

• There is no error.

Where is the mistake in solving this equation?

• There is no mistake.

• In line two when they got 12. It should stay a 3.

• In line 6 when they got 5. They should have added -2 to both sides and got -8.

• In line 4. They added 6x on the left sided but subtracted 6x on the right side.

What is the error?

• Adding 2x to 3x

• Subtracting 5 from both sides

• Adding 2x to -2x

• Dividing by 5 on both sides

Identify the steps to solve for b

• Add 6 to both sides and divide both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5
