From the question given;

5 = 2/5 m

25 = 2m

Divide both-side by 2

25 /2 = m

m = 25/2

Now to solve for H

( H + [ 1 4 -2 ] ) + [ 3 2 -6 ] = [-2 3 -1] + ( [1 4 -2] + [ 3 2 -6] )

( H + [ 4 6 - 8 ] )= [ -2 3 - 1] + [ 4 6 - 8 ]

( H + [ 4 6 - 8 ] = [ 2 9 -9 ]

Subtract [4 6 -8] from both-side

H = [ 2 9 -9 ] - [ 4 6 -8 ]

= [-2 3 - 1]

m x H = [ 25/2 * -2 25/2 * 3 25/2 * -1 ]

m x H = [ -25 75/2 -25/2 ]
