Not sure if you mean 7x 6y as in 7*6y=126, where * means "multiplied by" and you must solve for y or if you mean that we must solve for both x and y, but the answer to the part where you are solving 7*6y=126 is 3.
it equals -4n
9n-2=7n+50 7n+9n=50+2 16n=52 n= 3.25
8m + (4n - 6m) + 9n =8m + 4n - 6m + 9n =(8m - 6m) + (4n + 9n) =2m + 13n
3n x 3n = 9n if 9n = 36 then n = 36/9 = 4
The equation "9n equals 126" can be written as 9n = 126.
12
You need to get n alone.9n=45 → Divide by 9n=45/9n=5
you have 9n+17=-1 -17 -17 9n=-18 /9 /9 n= -2
54 / 9 = n n = 6
9n + 18 = 81 9n = 63 n = 7
-19 + 9 = -10n = -19n+9=-10-9 -9n=-19

9n+9=81 9n=72 n=8
9n - 9 = 45 9n = 45 + 9 = 54 n = 54 / 9 = 6
it equals -4n
it equals -15
