2x - y = 5 --- x + 3y = 7What is the value of the y-determinant?
what do they mean by y-determinent? does that just mean y? or something else

hartnn · Answer

have u learnt about determinants?

anonymous · Answer

no, i missed alot of school, last year, so that's why i have to be doing these online makeup courses...

hartnn · Answer

ok,using determinants,we can solve the system of linear equations
we can arrange the co-efficients of x,y and constant in the form of determinant....

this is system determinant,formed by co-efficients of x and y...if u can observr that....now i will draw x and y determinants....

anonymous · Answer

so the coefficients are the determinents?

hartnn · Answer

x determinant is formed by replacing column with x co-efficient to column with constants(on right side)|dw:1345567218527:dw|
