Suppose you want to use elimination to solve this system. 3x +11y = -1
(4x + 8y
= 6
By what numbers would you need to multiply the two equations in order to eliminate y? By what
numbers would you need to multiply the two equations in order to eliminate x instead? Drag and drop
the correct numbers and words into the boxes to complete the explanation.
You could multiply the first equation by
and the second equation by
and
then
the resulting equations to eliminate y. You might choose to eliminate x instead. To
do this, you would multiply the first equation by and the second equation by
and then
the equations.
