Combine Like Terms and Solve No Negatives

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 should be the first two steps to solve this equation? 2x +4(3x + 6) = 90

• combine 2x and 3x and then distribute the 4.

• subtract 6 from both sides and then divide by 4

• distribute the 4 and then combine like terms by addition

• combine 2x and 3x and then subtract 6 from both sides

What is the first step to solve this equation? (3n - 4) + (-2 + 2n) = 9 

• Combine 3n and -4 and also combine -2 and 2n

• Add 3n to both sides of the equation

• Subtract 2n from both sides of the equation

• Combine 3n and 2n and also combine -4 and -2

Which would NOT be an acceptable next step in solving this equation? −4x − 7 = 3x + 2

• Subtract 2 from both sides

• Combine -4x and 3x to make -1x

• Subtract 3x from both sides

• Add 4x to both sides

What is the first step to solve the following equation?

12x + 4x = 64

• Combine Like Terms
