i think ill choose x
so if you get x alone for one equation, you then replace what you get into the second equation and solve for y
so i mutiply 10x on all 3 of the first equation?
o.O? to get x alone? or?
to subtract it with the other equation?
are you trying to solve it by elimination?
no by substitution
if you get Y alone in the first equation it would be what the first person said y=2x-9 then you substitute the 2x-9 into the second equation getting 5(2x-9)=10x+45
10x-45=10x-45*
oh i kinda get it. then you multipy 5 on the parantesis
than you add like terms?
both sides equal each other if you combine like terms you get 0=0
:o o? wow. now i have to solve the other 1
good luck! hope it helped.
its sure did friend=)
