Question

SOMEONE PLEASEEEEE HELP .... GIVING BRAINILEST!!!

Find the value of M
Find the value of N

Answer 1

m = 5

n = 15

Explanation:

n + n+6 = 3m + 7m-14

2n + 6 = 10m - 14

2n = 10m -20

n = 10m/2 - 20/2

n (simplified) = 5m-10

we can let 'n' = 5m-10 using 'substitution':

3m = 5m-10

-2m = -10

m = 5

now we can find 'n':

n = 5m-10

n = 5(5)-10

n = 25-10

n = 15

CHECK:

3(5) + 7(5)-14 should equal 15 + 15 + 6

15 + 21 = 36

36=36 [checks out]
