Part 1: Explain, in complete sentences, how you would use the substitution method to solve the following system of equations. (4 points) Part 2: Provide the solution to the system. (2 points)

x + 5y = 3
2x + 9y = 4

Okay, i have tried this about 10 times now. i can't get it i keep coming out to 4,16, and 34.

How can you get three answers for two variables?

anonymous · Answer

so you see my problem?

mertsj · Answer

Yes.

anonymous · Answer

multiply the first equation by -2, add to second one

anonymous · Answer

oh wait, no the first times i got 4 & 16 than i got 16 and 34 and vise versa? but no other numbers?

anonymous · Answer

$$-2x-10y=-6$$
$$2x+9y=4$$
$$-y=-2$$
$$y=2$$

anonymous · Answer

how?!

anonymous · Answer

so solution to 
$$x + 5y = 3, 2x + 9y = 4 $$ is 
$$x=-7,y=2$$

anonymous · Answer

okkk okk hold on let me write that down~~~~~

anonymous · Answer

okay! got it

mertsj · Answer

Part 1: Explain, in complete sentences, how you would use the substitution method to solve the following system of equations. (4 points) Part 2: Provide the solution to the system. (2 points)  To solve by substitution, solve the first equation for x and replace x in the second equation with that expression.  The resulting equation will have only one variable and it will be x.  Solve that equation for x.  Replace x in either equation with that value and solve for y.

Satellite did Part !!

okay is it weird so say ilove you both?

mertsj · Answer

Part 1: Explain, in complete sentences, how you would use the graphing method to solve the following system of equations. (3 points)
First, solve each equation for y so that both equations are in the slope-intercept form, y = mx +b where m is the slope and b is the y intercept.  Mark the number b on the y axis and then follow the directions given by the slope which is rise/run.  Then draw the line.  Repeat with the second equation.

Part 3: Explain what the solution represents on the graph. (1 point)

The solution is the point where the lines cross on the graph.

mertsj · Answer

No.  It is not weird.  We love you too.
