Answer:
<em>System of Linear Equations with No </em><em>Solutions</em>
The red line is the graph of y=4x+ 2, and the blue line is
the graph of y=4x+5. When two equations have the
same slope but different y-axis, they are parallel. Since
there are no intersection points, the system has no
solutions.
hope it help ❤️

We have such system of eq
First lets solve second eq
7x=21 /:7 divide both sides by 7
x=3
Now we can substitute it to first equation
9x-2y=19
9*3-2y=19
27-2y=19 /-27 subtract 27 both sides
-2y=-8 /:(-2) divide both sides by -2
y=4 - its the answer
