Respuesta :

7m - 3n

m = 3, n = 2

Replace m and n with the appropriate numbers:

7(3) - 3(2)

Multiply both sides:

21 - 6

Subtract:

21-6 = 15

Remember to follow PEMDAS.

Note that: m = 3, n = 2

Plug in the corresponding numbers to it's variable

7m - 3n

7(3) - 3(2)

Simplify each term by multiplying

7 x 3 = 21

3 x 2 = 6

Subtract:

21 - 6 = 15
