Lev was incorrect because both sides of equation are not equal when putting (9,4) in the equation.
Step-by-step explanation:
Given equation is:
[tex]3y-2x = 19[/tex]
We have to check if the point (9,4) is the solution to the equation or not
So putting x=9 and y = 4 in equation
[tex]3(4)-2(9)=19\\12-18 = 19\\-6 = 19[/tex]
He was wrong when he said that (9,4) is the solution to the equation because both the sides of the equation are not equal when putting the point in the equation.
In order for a point to be the solution of an equation, both sides of the equation should be equal after putting the point.
Lev was incorrect because both sides of equation are not equal when putting (9,4) in the equation.
