whats the elimination method to solve a system of equations

Question

anonymous · Answer

system of equations is 
3+8b=17
a+3b=2

anonymous · Answer

multiply the bottom equation by 3 to make it become 3a+9b=2, that way you can subtract the 2 equations and eliminate the a

Actually, the first equation you posted only has one variable in it.

anonymous · Answer

or you can multiply by -3 and add the two equations lol, I personally don't like multiplying by negatives so i multiply by positive

two equations are simplified by adding them or subtracting them.eliminates one variables so that the other variable can be found.
