Answer: The answer is $4.20
Step-by-step explanation:
(+3x+4y=2)
(+4x-4y=12)
-----------------
7x = 14
-----------------
7
X=2
3(2)+4y=2
6+4y=2
4y=-4
Y=-1.
Or you can plug x into the other equation.
4(2)-4y=12
8-4y=12
-4y=4
Y=-1.
n/-5 - 9 = 2
move -9 to the other side
sign changes from -9 to 9
n/-5-9+9=2+9
n/-5=2+9
n/-5=11
multiply both sides by -5/1 to find n
(n/-5)(-5/1)=11(-5/1)
n=-55
answer: n=-55
