Why is the first step when solving 2x - 15 - 4x = 3 to combine like terms?
A. Because there are like terms (the variables) on the same side of the equation.
B. Because there are like terms (the constants) on the same side of the equation.
C. Because there are like terms (the variables) on opposite sides of the equation.
D. Because there are like terms (the constants) on opposite sides of the equation
A. Because there are like terms (the variables) on the same side of the equation.
In this equation, the terms 2x and -4x are like terms because they both contain the variable x. By combining these like terms, the equation can be simplified before solving for x.
