Question

What method would you choose to solve the

equation 2x- - 7 = 9? Explain why you chose this
method.

Answer 1

Answer: Method: Multi-step equations.

Explanation:

2x- (-7) = 9

Subtract 7 from both sides.

2x + 7 - 7 = 9 - 7

You end up with 2x = 2

Divide 2 from both sides.

x = 1.

Multi-step because you have to add seven and divide two from both sides.

Answer 2

x = 1

I am not sure about what method

Explanation:

2x - -7 = 9

2x + 7 = 9 Subtract 9 from both sides

2x = 2 Divide both sides by 2

x = 1
