A pair of equations is shown below: y = 3x − 5 y = 6x − 8 Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points) Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points)

I think that you can solve your system of equation using the substitution method

OpenStudy (anonymous):

That is what I thought.

OpenStudy (anonymous):

Now I just need help solving it. @Michele_Laino

OpenStudy (michele_laino):

it's very simple, you just have tha value for y, for example from the first equation: 3x-5, so please, you have to substitute this value into the second equation, please write what you get

OpenStudy (michele_laino):

try please!

OpenStudy (anonymous):

The answer is 1 and -2

OpenStudy (michele_laino):

Ok! x=1 and y=-2

OpenStudy (michele_laino):

the point (1,-2) is the point in which the lines intersect each other

OpenStudy (anonymous):

So now in part A i must show my steps...

OpenStudy (michele_laino):

(1) \[3x-5=6x-8\] (2) \[3x=3\] (3) \[x=1\] (4) \[y=3*1-5=6*1-8=-2\]
