Question

Given the equations 9x+34y=6 and 2x+12y=9, by what factor would you multiply the second equation to eliminate y and solve the system through linear combinations?

Answer 1

HI!!

Answer 2

what would you multiply \(12\) by to get \(-36\)?

Answer 3

to eliminate y, you must get the same coefficient of y in both equations

so since we use the second equation we want to turn 12 into 32
to do this we make an expression
12x=34
x=34/12=17/6

so we multiply by 17/6 to get the same coefficient
then you can simply eliminate y
