Answer: 25
<u>Step-by-step explanation:</u>
7(x - y) - 3(2 + 2x)
= 7x - 7y - 6 - 6x
= x - 7y - 6
for x = 3, y = -4
3 - 7(-4) - 6
= 3 + 28 - 6
= 31 - 6
= 25
X= 14 + 9y over 2
y= -x - 7 over 6
To multiply fraction do top x top and bottom x bottom
so convert
into
then do
I hope this helps you
-4x-2y+4x+8y= -12-24
6y= -36
y= -6
-4x-2. (-6)= -12
-4x+12= -12
-4x= -24
x=6
(6, -6)
