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 the same side of the equation. Because there are like terms (the constants) on the same side of the equation. Because there are like terms (the constants) on the same side of the equation. Because there are like terms (the variables) on opposite sides of the equation. Because there are like terms (the variables) on opposite sides of the equation. Because there are like terms (the constants) on opposite sides of the equation. Because there are like terms (the constants) on opposite s
ides of the equation.
Combining like terms simplifies the equation and makes it easier to isolate the variable and solve for it. It reduces the number of terms in the equation and helps in organizing the information to find the solution more efficiently.
