Multiply the entire second equation by -1 and then cancel out the 6x
OpenStudy (anonymous):
this will equal 8y=18 now divide 8 by both sides and then you get 9/4
OpenStudy (anonymous):
Y=9/4 so you just plug it in in any of the two equations to get the value of x
OpenStudy (anonymous):
The 9/4 is negative btw
