What is the difference between algebra equations and expressions?
expressions don't have an equal sign and equations do
How do you solve an algeraba problem?
There are lots of different types of problems in algebra; you have to learn each type separately. For example, how to add similar expressions; how to multiply expressions; how to factor polynomials; how to solve equations; etc.
How are algebraic expressions and equations alike?
Algebraic expressions are the written relations of or between variables. For example, x2, 1/x, and x + y + z are all algebraic expressions. Algebraic equations are simply algebraic expressions that equate to something. For example, x2 = 4, 1/x = y, and x + y + z = 42 are all algebraic equations. In general, one differentiates algebraic expressions from exponential, trigonometric, hyperbolic, and logarithmic expressions by requiring algebraic expressions to be confined to polynomial expressions. I've added a link regarding polynomials below.
Do the equations 2x 4y9 and -4x-8y4 have a solution?
The given expressions can't be considered to be equations because there are no equality signs.
Does an equation have an equal sign?
yes. equations have an equals signs and expressions don't
