What is 3m plus 2n equals 8?

Answer 1

this is called an algebraic expression. the letter "m" and "n" are called variables. you need to find out what number you can replace the "m" and "n" buy so the equation on the left side equal 8

lets try m=3 and n=2

If we do this then... (3 x 3 ) + (2 x 2) = 8

Is this correct.. well lets see... 3 times 3 is 9 and 2 times two is 4. if you add 9 and 4 that equals 13. so these numbers are not correct.

try m=2 and n=1

If we do this then... (3 x 2) + (2 x 1) = 8

Is this correct... well lets see... 3 times 2 is 6 and 2 times 1 is 2. if you add 6 and 2 that equals 8. these are the correct numbers that "m" and "n" should equal!
