Y=4x+5 and y=4x-5 has no solution
What are Linear Equations in two Variables?
The formula for a two-variable linear equation is Ax + By + C = 0, where A and B are the coefficients, C is a constant term, and x and y are the two variables, each with a degree of 1. A linear equation with two variables, for instance, is 7x + 9y + 4 = 0. These two linear equations are referred to be simultaneous linear equations if we take them into consideration.
Steps
[tex]Y=4x+5\\ Y=4x-5[/tex]
Substitute y=4x+5
[tex][4x+5=4x-5][/tex]
Refine [tex][4x+5=4x-5][/tex]
-10=0
-10=0 is a false ,therefore the system of a equation have no solution
