The answer is -2. You add 7 to negative 9.
Put x and y on one side.
y = -3/10x - 8
Add 3/10x to both sides.
3/10x + y = -8
Because there are no fractions in Standard Form, multiply everything by 10.
3x + 10y = -80
Answer:
n= 3/5
Step-by-step explanation:
This can be easily done by cross-multiplying(and also beneficial to get rid of fractions):
(5n+1)(2) = 1(8)
10n +2 = 8
10n = 8-2
10n=6
n = 6/10
Simplify:
n = 3/5
Hope this helps!
