Answer:
X+ 7 = 21 - 7 - 7x = 14
Step-by-step explanation:
replace x values and y values with the answer choices.
since the coordinate pair 
it is safe to assume that d will be the correct answer.
use the graph to confirm that the solution is (1,0)
the blue line intersects at (1,0), so the solution for the system of equations is (1,0)
Answer:

Step-by-step explanation:
If he ate 4 of them, but it means he ate 2/5 muffins,
4 muffins = 2/5 muffins
You substitute x muffins for how much muffins she baked in all -
2/5* x muffins = 4
2/5 multiply by 2/5 to cross it out. Do the same to the other side.
x= 4 *5/2
x = 10 muffins
So there were 10 muffins in all
