A row operation is performed on a matrix as shown below. [ 2 -1 1 | 4 ] [0 -3 x | -18 ]
[ 1 1 1 | 11 ] --> [ 1 1 1 | 11 ]
[4 -2 2 | 5 ] [4 -2 2 | 5 ]

What is the value of x?
a. -2
b. -1
c. 0
d. 3

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
