x=-2
y=2/5
using inverse matrix and find the determinant.
1)find determinant
2)find inverse of the matrix given
3)mutiplay the determinant with the inverse matrix
4)pre-mutiply the result on both side
x=-2
y=2/5
x=-2
y=2/5
Using inverse matrix
x=-2, y=2/5
Find the determinant and work out the inverse. After which, pre-multiply both sides to find x and y.
x=-2 & y=2/5
Find the determinant after which find the inverse matrix then pre-multiply the both side. Hence solve x& y.
x= -2
y= 2/5
find determinant, inverse of the matrix, then pre-multiply
x= -2
y= 2/5
it is by using inverse matrix and finding the determinant.
(:
x= -2
y= 2/5
Didnt see the "Do this by 7 Feb" hope you dont mind.
x = -2, y = 2/5
it is by using the inverse matrix and then pre-multiplying both sides.
x= -2
y= 2/5
find determinant and find inverse matrix then pre-multiply. Finally solve and find x and y.
x= -2
y= 2/5
use inverse matrix and find the determinant then pre multiply on both side
x= -2, y= 2/5
use inverse matrix and find the determiant then pre-multiply on both side
x= -2
y= 2/5
find determinant then find inverse of the matrix, then pre-multiply
x=-2
y=2/5
by using inverse matrix method and finding the determinants
x= -2
y= 2/5
Find the Determinant.
Use inverse matrix to pre-multiply both sides.
x=-2
y=2/5
determinant==>inverse==>pre-multiply
x=-2
y=2/5
it`s by using inverse matrix and find the determinant, then pre-multiply.
x=-2
y=2/5
Step 1)Find determinant
Step 2)Find inverse matrix
Step 3)Pre-multiply on both sides
Last but not least, find the x and y.
1st, find the inverse then find the determinants and multiply them together
the answer is x=-2 and y=2/5
x=-2
y=2/5
use inverse matrix and find determinant.
x=-2 y=2/5
find inverse of matrix and the determinant.
x=-2
y=2/5
find inverse of matrix and thn fnd the determinant
x=-2
y=2/5
find inverse of matrix and
find determinant
