Answer:
your answer is C.
Step-by-step explanation:
The values of x = -6 and y = 6 satisfy both the equations; therefore, (-6, 6) is the solution. The correct option is a)
<h3>Simultaneous linear equation</h3>
From the question, we are to determine the solution of the given system of equations
The given system of equations are
2 x + 3 y = 6 ------- (1)
x + 3 y = 12 ------- (2)
From equation (2)
x + 3y = 12
Then, we can write that
x = 12 - 3y --------- (3)
Substitute this into equation (1)
2x + 3y = 6
2(12 -3y) + 3y = 6
24 - 6y + 3y = 6
24 -3y = 6
24 - 6 = 3y
18 = 3y
∴ y = 18/3
y = 6
Substitute the value of y into equation (3) to get the value of x
x = 12 - 3y
x = 12 -3(6)
x = 12 - 18
x = -6
∴ x= -6 and y = 6 ; Thus, (-6, 6) is a solution
Hence, the values of x = -6 and y = 6 satisfy both the equations; therefore, (-6, 6) is the solution. The correct option is a)

Answer:
So, 2/14 are red and pink but if the rest are white the 12/14 are white.
Step-by-step explanation:
If
, then
for
. This is definitely the case, since
is undefined if
. Now,
, so we have
or
and
. One of these solutions is larger than 1 in absolute value, but
, so we omit that solution, leaving us with
for integers
, which follows from the fact that
has period
.
$37 times 0.07 is $2.59
Add the sales tax and total price and you will get $39.59
Good luck!
