Jeremiah is correct. The first step in solving this equation is to get all the variables on one side of the equation. By subtracting 6x from both sides, you eliminate the variable from one side of the equation.
6x - 2 = -4x + 2
Subtract 6x from both sides:
-2 = -10x + 2
If Spencer were to add 4x to both sides first, the equation would become:
6x - 2 + 4x = 2
10x - 2 = 2
This is not helpful in simplifying the equation or isolating the variable x. Therefore, Jeremiah is correct in his approach to subtract 6x from both sides as the first step.
In the equation 6x – 2 = –4x + 2, Spencer claims that the first step is to add 4x to both sides. Jeremiah claims that the first step is to subtract 6x from both sides. Who is correct? Explain.
