Is the question typed correctly? I mean for the first equation 5u + 2u = -17
multiply first by 3 & second by 5
it can be 5u+2v=-17
the question should be 5u + 2v = -17
k then subtract first eq from 2:)

follow my or @Callisto step 1 by 1:)
Okay, the simpler way to do it is to multiply the second equation by 2. Then subtract (1) by (2) That is 5u + 2v = -17 -(1) 3u + v = -8 -(2) (2)x2 - (1) 2( 3u + v ) - (5u + 2v) = 2(-8) - (-17)
yes right
got it @marie52 ????
yes! Thanks!
