Solve, using the substitution method. y + 2x = 7 14 – 4x = 2y The solution is (1, 5) The solution is (21, 0) There are an infinite number of solutions. There is no solution.

TheSmartOne (thesmartone):

Have you gotten an answer?

OpenStudy (anonymous):

can i get one sec to try

TheSmartOne (thesmartone):

Sure thing :D

OpenStudy (anonymous):

there is no solution?

OpenStudy (anonymous):

solve for y y=-2x+7 plug in the the second equation and solve for x once you have the value of x plug it to one of the original equations and solve for y

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

welligya...... your agreat team worker

OpenStudy (anonymous):

I got it right?

OpenStudy (anonymous):

@TheSmartOne @bere1

OpenStudy (anonymous):

y=-2x+7 plug in 14-4x=2y 14-4x=2(-2x+7) --> 14-4x=-4x+14 --> 0=0 no solution

OpenStudy (anonymous):

you were right the first time i was just letting you know how to do it :)

OpenStudy (anonymous):

right

OpenStudy (anonymous):

oh ok thhanks :)
