Answer:
Step-by-step explanation:
Given is the system of equations:

a) Coefficient matrix is
7 3
-6 -3
b) |A|= -21+18=-3
c) Inverse =
1 --1
2 -7/3
c) Solution = product of inverse matrix * (12 4) Transpose
X1 = 16 and X2 =-100/3
Step one- distribute
6y-9=27
Step 2- subtract 9 on both sides
6y=18
Step 3 divide on both sides
Y=3
Answer:
y=x
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-1)/(5-1)=4/4=1
slope is 1
y-y1=m(x-x1) where m=slope
y-1=1(x-1)
y-1=x-1
y=x-1+1
y=x
