Solve the following system using augmented matrix methods:
−4x+8y=−8, −8x+16y=−18

The initial matrix is:

(b) First, perform the Row Operation 1−4R1→R1

(c) Next, perform the operation +8R1+R2→R2. The resulting matrix is:

(d) Finish simplifying the augmented matrix. The reduced matrix is:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
