Answer:
x = 4, y = 9.
Step-by-step explanation:
3x -2y = -6 and y = x+5
Substitute y = x + 5 in the first equation:
3x - 2(x + 5) = -6
3x - 2x - 10 = -6
x = -6 + 10
x = 4
So y = 4 + 5 = 9.
Mx = -6
The other number (x) will be:
x = -6/m
56 divided by 7 = 8
8 multiplied by 6
=48

Answer:
(d) b/a
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
__
Then the expression simplifies to ...
b^-2/(ab^-3) = b^(-2-(-3))/a = b^1/a = b/a
