For the following system, if you isolated y in the first equation to use the Substitution Method, what expression would you substitute into the second equation?

anonymous · Answer

if you solve 1st eq for y, then y=4x-8

whts the answer

4x − y = 8 
2x + 3y = 9 
------------


multiply the top equation by 3

12x-3y = 24
2 x+3y = 9
-----------

add vertically

(12+2)x +0y=24+9

14x = 33

x = 33/14

plug back into either equation to get y.
