Answer:
no ............mmmmmmmmmm.
Answer:
Substitution, but this system of equations has no solution.
Step-by-step explanation:
2x-4y=10
2y+6=x
----------------
2(2y+6)-4y=10
4y+12-4y=10
12=10
no solution.
You rented 12 movies ( 68.88 - 45.00 = 23.88 then divide 23.88 by 1.99 to get 12)
Use the distributive property and collect terms.
= x·6x -x·8y +y·6x -y·8y
= 6x² -2xy -8y²
Well I know that the square root of 121 is 11
