two or more equations used together in the same
problem and
having unknown quantities of the same
value. Equations are statements of equality between two quantities, as shown by the equal sign ( = ).
(mathematics) two or more equations containing
variables for which the same
values can make each of the equations true. An
equation is a
statement of equality between two quantities; for
example, 2x@y=1, where x and y represent
numbers. In
order to solve this
equation, one would figure out which
numbers inserted into the
formula would give the correct answer. In this
case, if x stood for the number 2 and y stood for 3, the
equation would be true 2x2 (4)@3=1. Thus, x=2 and y=3 would be a
solution of the
equation. Simultaneous equations are equations that are satisfied by the same
solution. For
example, the
solution for both 2x@y=1 and x+2y=8 is x=2 and y=3. You get simultaneous equations, of all things, in
calculus, and this is supposed to explain something.
