Question

the method that involves solving one equation for one variable and substituting that expression into the other equation is called ______.

the point where two lines intersect on a graph representing the solution to a system of equations is called the ______ point.

when using elimination to solve a system of equations, you add or subtract the equations to ______ one variable.

a system of equations with no solutions is called an ______ system.

a system of equations that has infinitely many solutions is called a ______ system.

Explanation:

First Question:

The method of solving one equation for a variable and substituting that expression into another equation is a fundamental technique in solving systems of equations, known as substitution.

In a system of equations represented graphically, the point where the two lines intersect is the solution to the system, called the solution point.

The elimination method in solving systems of equations involves adding or subtracting equations to eliminate one variable, simplifying the system to solve for the remaining variable.

Answer:

substitution
