Best ResponseYou've already chosen the best response.0by the simultaneous way look i'll solve u one as an example & u do the others on the same Pattern...........so let's take no.2 2x+3y=8 in the simultaneous way the value of (X) or (y) x+y=4 must be equal in the 2 equations to be cancelled therefore we will multiply equation 2 time 2 (x+y=4) X 2 = 2x+2y=8 so......2x+3y=8 2x+2y=8 so by adding the 2 equations we get that 5y=0 so y=0 so x=4
