Answer:
the answer of this question will be 0.2
I think the answer is 0.4
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
Answer:
6
Step-by-step explanation:
y + 1
= 7
y +
= 
y = 40/6 = 20/3 = 6
