Maybe if multiply 80 by 3 so you can find one of the answer then do it algebraic
You solve this by plugging one equation into the other. Usually you have to rewrite one equation to make this work. In this case I choose to rewrite y-4x=0 as y=4x.
After plugging it into the second, you get:
3x + 6*4x = 9 => 27x = 9 => x=1/3
Putting this solution back into y=4x gives us y=4/3
Step-by-step explanation:
40=1.6d-3.2
43,2=1.6d
27=d
