hello :)

usukidoll · Answer

so the question is about Mindy solving 
y = x – 4
y = 2x – 3
using the elimination method. 

and the question asks what number do we need to multiply for y = x-4 to eliminate x

usukidoll · Answer

notice that the second equation has y =2x-3, so that gives a clue on what to multiply by for the first equation
