a=(2m+n)i+j b=10i+(3m-2n) a=b m=? n=?

jawab langsung aja lah ahahaha

dik :
a = b

dit :
m ?
n ?

jwb

a = b
(2m + n )i + j = 10i + ( 3m - 2n )
2m + n + i + j = 10i + 3m - 2n
2m - 3m + 2n + n + i - 10i + j = 0
- m + 3n - 9i + j = 0

a.) - m = - 3n + 9i - j
m = 3n - 9i + j

b.) 3n =( m + 9i - j )
n =( m + 9i - j )/3


semoga membantu yah
