PLease ,Please ,Please help me solve this problems
#1
Since x = 3y-4,
-3(3y-4)+4y = -3
now just solve for y and then x
#2
Since x = 4+4y,
-(4+4y) = 4y=-4
or something
Again, solve for y, then x
hey, come on. Surely you can do
-3(3y-4)+4y = -3
-9y + 12 + 4y = -3
-5y = -15
y = 3
Now, x = 3y-4 = 9-4 = 5
Now do #2 the same way.
