Answer:
y = 4x-9
Step-by-step explanation:
16x-4y-36 = 0
-4y = -16x+36(subtract 16x from both sides and add 36)\
y = 4x-9(divide both sides by -4)
25 and -12 because when you subtract 12 from 25 you will get 13 and when you multiply 25 by -12 you will get -300
solve this answer by using substitution. set the first equation to x=-y+4 then substitute -y+4 for x in the second equation.
2(-y+4) + 3y=0
-2y+8 + 3y=0
y+8=0
y=-8
now use -8 and solve for x
x+(-8)=4
x=12
