1st is 1 1/2 2nd is 2 and 3 is 2
Solution is where the lines intersect. It's is (-2 , 1)
Answer is B.(-2,1)
Part A: -x+y=5
+x +x
y=x+5
4x+x+5=10
5x+5=10
-5 -5
5x=5
x=1
1(-x) +y=5
-1+y=5
+1 +1
y=6
The solution is (1,6)
Part B:
-x+y=5
-1+6=5
5=5
4x+y=10
4(1)+6=10
4+6=10
10=10
Id say |x|=5, that's my guess
1/2x + 13 at least I think not so sure
