See the solution process below:

Explanation:

To solve this problem we need to substitute #color(red)(2)# for #color(red)(k)# in the expression and we need to substitute #color(blue)(5)# for #color(blue)(m)# in the expression and then evaluate the expression:

#10color(blue)(m) - 2color(red)(k)# becomes:

#(10 * color(blue)(5)) - (2 * color(red)(2)) => 50 - 4 => 46#
