A statement that two quantities are equal is called an equation. In mathematics, an equation typically consists of two expressions separated by an equal sign, indicating that the values of the two expressions are the same. Equations are fundamental in algebra and are used to solve for unknown variables by performing various operations to maintain the equality of the quantities involved.
An equal sign (=) with a slash through (/) represents that two expressions are disproportional.
No, but a variable can have more than one value in an inequality such as x > 10. In that inequality, x can be 11, 12, 13, 14, or anything else higher than 10.That is not to say, however, that the same variable can't be equal to two different expressions or formulas. The equations x=10 and x=y+5 are completely valid. In fact, those expressions imply that 10=y+5, or that y=5.
no algebraic expressions do not have equal signs but equations do.
No they do not, equations have equal signs.
