Question

PLEASE ANSWER AS FAST AS YOU CAN!Look at the equation: 7x + 2 = 3x − 12 Sam says that the first step is to subtract 3x to both sides of the equal sign. Kue says that the first step is to subtract 7x to both sides of the equal sign. Who is correct? Can both of them be correct? Explain.

Answer 1

Both are correct.

Explanation:

They are both correct, since the first step to solving the equation would be to combine like terms. By subtracting either 3x or 7x from both sides of the equation, they are combining the like terms.
