Which graph best represents the solution to the system of equations shown below?
goldfiish [28.3K]

First find the x and y values because where the lines will intersect, they share the point of the intersection so they will share the x and y coordinates.

Rearrange equations

4x + y = 19

- 2x + y = 1

To cancel y, we must do equation 1 minus equation 2. Similarly:

4x -  - 2x = 4x + 2x = 6x

19 - 1 = 18

6x = 18

x = 18 \div 6 = 3

So the x coordinate is 3.

The y coordinate can be found with substitution of x into one of the equations:

y = 2x + 1 = 2(3) + 1 = 7

So where the two lines intersect is at the point (3, 7), which is the solution to the equations.

How do you get why by itself in this equation? 4x+5y=5
Alja [10]

Answer:

first we get y on one side by itself.

4x+5y=5

we'll move x to the other side.

4x-4x+5y=5-4x

simplify.

5y=5-4x

now we get rid of the coefficient on y.

5y/5=(5-4x)/5

simplify.

y=5/5-4x/5

y=1- \frac{4}{5}x

The answer is y=1-\frac{4}{5}x
