X+y=2 (label equation one)
x-y=4 (label equation two)
y=-x+2 (equation one rearranged, label this equation equation three)
sub 3 into 2
x-(-x+2)=4
x+x-2=4
2x-2=4
2x=6
x=3
sub x=3 into equation one
3+y=2
y=-1
therefore x=3 and y=-1

Answer:
c = 9/16
Step-by-step explanation:
<h3>step1</h3>
(a-b)²
a² - 2ab + b²
here a = x
b = ?
so
x² - (2)(x)(?) + ?²
Now we can see that -(2x)? = -3x/2
-2x? = -3x/2
cancel -x on both sides
2? = 3/2
? = 3/2 * (2)
? = 3/4
so b = 3/4
<h3>step2</h3>
(x² - 3x + 9/16) = (x-3/4)²
so from the expression we can see that C = 9/16
