Question

4m+3n=12 what this the solutions ofthe given example
​

Answer 1

Step-by-step explanation:

$4m + 3n = 12 \\ 4m = 12 - 3n \\ m = \frac{12 - 3n}{4} \\ \\ 4m - 3n = 12 \\ 4( \frac{12 - 3n}{4} ) - 3n = 12 \\ \frac{4(12 - 3n)}{4} - 3n = 12 \\ \: four \: cancels \: out \\ 12 - 3n - 3n = 12 \\ 12 - 6n = 12 \\ - 6n = 12 + 12 = 24 \\ n = \frac{24}{ - 6} \\ = n = - 4$

m=12-3n/4

m=12-3(-4)/4

m=12+12/4

m=24/4

m=6
