Matrices A and B are shown below.
BabaBlast [244]
The first thing you must remember is that the product of matrices is done by multiplying rows by columns.
 For this case, the AB matrix is
 AB = [1 0 0; 0 1 0; (x + 1) 0 y]
 Equalizing the identity matrix we have
 AB = I
 [1 0 0; 0 1 0; (x + 1) 0 y] = [1 0 0; 0 1 0; 0 0 1]
 Therefore we have
 x + 1 = 0
 y = 1
 The values of x and y are
 x = -1
 y = 1 
the answer is 
 X=-1
 Y=1

Pls pls pls pls pls help​
Arturiano [62]

Answer:

y=\frac{1}{2}

Step-by-step explanation:

4(y+1)= \frac{3}{1-y}

4y+4= \frac{3}{1-y}

(4y+4)(1-y)= 3

4y(1-y)+4(1-y)=3

4y-4y^{2} +4-4y=3

-4y^{2}=3-4

4y^{2}=1

y^{2} = \frac{1}{4}

y=\sqrt{\frac{1}{4} }

y=\frac{1}{2}
