A bivariate equation.
Multivariable equation
add one to the problem
An equation with more than one variable is called a multivariate equation.
Simultaneous equation* * * * *No, simultaneous equations are two or more equations that have all to be true at the same time (simultaneously) for the solution.An equation with more than one variable is a multivariate equaion.Area = 0.5*Length*Height or a = 0.5*l*h for the area of a triangle has more than one variables, but it is certainly not simultaneous.An equation with a variable is called a single variable equation. An equation that has more than one variable is called as a multi-variable equation. A polynomial equation has one variable in different powers: a common example is quadratic equations.
A = b.
well, an equation with one variable is a one step equation and an equation with more than 2 variables is a multi-step equation
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
a formula
True
more than one variable
ordinary differential equation is obtained only one independent variable and partial differential equation is obtained more than one variable.
