Simplifying Equations
Why is the first step when solving 2x - 15 - 4x = 3 to combine like terms? Because there are like terms (the variables) on the same side of the equation. Because there are like terms (the variables) on opposite sides of the equation.
1 answer
Because combining like terms simplifies the equation and makes it easier to isolate the variable on one side of the equation.
