Answer:

(-2, 4)

Step-by-step explanation:

In the first equation substitute -2x for y, obtaining:  5x - 9(-2x) = -46

Then 5x + 18x = -46, or  23x = -46, resulting in x = -2

Since y = -2x, y = -2(-2) = 4

The solution is (-2, 4)

The value of x coming is -2 and the value of y=4 by plotting the equations 5x-9y=-46 and y=-2x.

What is a equation?

A statement that the values of two mathematical expressions are equal.

How to plot graph of an equation?

First we have to find the values of x and y as we can see in the figure1.

By plotting these points we can make graph of both the equations and the intersection point will be the solution of these equations.

Blue line is the line of the equation 5x-9y=-46 and the green line is the line of the equation y+2x=0
