Hey, you should be getting to be abke to do these.
subtract the second equation from the first to get rid of u
3 u + v - 3 u = 13 - v - 29
v = - v - 16
2 v = -16
v = -8
then
3 u -8 = 13
3 u = 21
u = 7
solve the system of equations by graphing. then classify the system as consistent or inconsistent and the equations as dependent or independent.
3u+v=13
3u=v+29
What is the solution of the system of equations?
