Answer:
the solution of the system is:
x = 1 and y = 2.
Step-by-step explanation:
I suppose that we want to solve the equation:
-6*x + 6*y = 6
6*x + 3*y = 12
To solve this, we first need to isolate one of the variables in one of the equations.
Let's isolate y in the first equation:
6*y = 6 + 6*x
y = (6 + 6*x)/6
y = 6/6 + (6*x)/6
y = 1 + x
Now we can replace this in the other equation:
6*x + 3*(1 + x) = 12
6*x + 3 + 3*x = 12
9*x + 3 = 12
9*x = 12 - 3 = 9
x = 9/9 = 1
Now that we know that x = 1, we can replace this in the equation "y = 1 + x" to find the value of y.
y = 1 + (1) = 2
Then the solution of the system is:
x = 1 and y = 2.
2-1 reversed is turning it around : 1-2 which equals -1 because there is one left over. B is your answer and hoped I helped!
<span>Let's start with basic definitions:
1 inch-----0.0833333 ft
If 0.375 Ft- represents 0.25 inches
then 1 foof-x inches
0.25 inches x 1 ft / 0.375 ft: 0.66666666666667 (2/3) inch
1 foot is represented by 2/3 of an inch</span>
The answer is negative because, ( -81/-9) =(+9). -(+9) = -9. Maybe for got the - sign before the equation
