Like or unlike? Simplify 5x + 3y − 2x + y. Find the value.

Algebraic expressions games

A term is a number, a letter, or their product: 5, x, 3xy, −2a².
Like terms have the same letters with the same powers (3x and −7x); unlike terms do not (3x and 3y).
Add or subtract only like terms: 5x + 3y − 2x + y = 3x + 4y.
Monomial (one term), binomial (two), trinomial (three), polynomial (one or more).
To find the value, put the number in place of the letter: if x = 2, 4x + 1 = 9.

For Class 6 to 8 (NCERT Ganita Prakash 7, “Expressions using Letter-Numbers”). Practice answers are computed by a program.
