Question

when we consider two linear equations in two variables then such equation are called as ____________​

Answer 1

Answer:

In order to investigate situations such as that of the skateboard manufacturer, we need to recognize that we are dealing with more than one variable and likely more than one equation. A system of linear equations consists of two or more linear equations made up of two or more variables such that all equations in the system are considered simultaneously. To find the unique solution to a system of linear equations, we must find a numerical value for each variable in the system that will satisfy all equations in the system at the same time. Some linear systems may not have a solution and others may have an infinite number of solutions. In order for a linear system to have a unique solution, there must be at least as many equations as there are variables. Even so, this does not guarantee a unique solution.

Answer 2

The answer is 'simultaneous equations.'

• When two variables are used, and two such equations are solved together, they are called simultaneous equations.

• They can either be solved by the elimination method or the substitution method.

• It is possible to find the values of the two variables using the method of simultaneous equations.
