If you wanted to eliminate the y variable by adding the two equations in the following system, what could be your first step?

5x − 6y = 6
x − y = 12

Add the two equations together

Multiply the second equation by −6

Multiply the first equation by −6

Multiply the second equation by 6

ganeshie8 · Answer

you need to have opposite coeffecients for y in both equations
so that when u add, they get eliminated

-6

speak out a bit more...  :)

anonymous · Answer

idk can u solve the questions and show mw how to do it

ganeshie8 · Answer

you're mostly there,

-6 is the coeffecient of y in the first equation

ganeshie8 · Answer

-1 is the coefficient of y in the second equation

ganeshie8 · Answer

but you want to make it +6
so u need to multiply the second equation with -6

anonymous · Answer

like show me the steps how to do it

ganeshie8 · Answer

the question doesnt ask u to solve it as such
