m*4+244=1000

Answer 1

$584-9n=476 \\ -9n=476-584 \\ -9n=-108 \\ n=-108:(-9)\\ n=12 \\ 4m+244=1000 \\ 4m=1000-244 \\ 4m=756 \\ m=756:4 \\ m=189.$

Answer 2

$\displaystyle a).584-9n=476 \\ -9n=476-584 \\ -9n= -108 \\ n= \frac{-108}{-9} \\ n=12 \\ b).m\cdot 4+244=1000 \\ 4m=1000-244 \\ 4m=756 \\ m= \frac{756}{4} \\ m=189$
