A student was trying to find the solution to a system of equations, but they were incorrect. Their explanation is shown below.
3x +4y = 10
3x + 4y =2
There are infinite solutions. When I subtract the equations, I get 0x + 0y = 8, so I know that there are infinite solutions to this system of equations.
Explain the mistake that the student made:

Answer:
Solving systems of equations
There are four methods for solving systems of linear equations:
a. graphical solution
b. algebraic solution
c. elimination method
d. substitution method
That's why the student made a mistake because he / she didn't follow the solving system of equations. He / she just did his / her own solving method that is not appropriate for the equation above.
Step-by-step explanation:
