If this is a triangle the the measure of angles 11 and 6 could be any number between 1 and 60
Answer:
Fully simplified it equals 4x^2 -21x -18
Explanation:
-You need to distribute the x to all of the terms in the second binomial and you also need to distribute -6 to all the terms in the second binommial giving you 4x^2 +3x - 24 -18
-You combine like terms to simplify and your answer is 4x^2 -21x -18

Step-by-step explanation:
Step 1 : Taking L.H.S(Left Hand Side) we have,
... equation (1)
Step 2 : As we know, 
Therefore,
by substituting value in equation (1), we have

Step 3 : As, L.H.S = R.H.S
Hence Proved,

2x+ 2y= 2; -4x+4y= 12
X + y= 1 ; -x+ y= 3 ==> y= 3+ x
X+ (3+x) =1
2x = 1-3= -2 ==> x= -1
Y= 2
