A coefficient is the number multiplying a variable in a term — like 7 in 7x. Learn the definition, how to spot coefficients, and how to combine like terms.
Solve it with the AI Math SolverIn a term, the coefficient is the numeric factor and the variable is the letter factor. The coefficient tells you how many of the variable you have and scales its effect.
Terms with identical variable parts are called like terms. You combine them by adding their coefficients — the algebraic version of counting up matching objects.
A coefficient is the number multiplying a variable in a term. In 7x, the coefficient is 7; in −3y², it is −3.
Sort the terms by their variables and add the coefficients of like terms. For 2x + 3x, the coefficients 2 and 3 add to give 5x.
