-2x + 6y = 6
6y - 6 = 2x
6(y-1) = 2x
(1/2) * 6(y-1) = 2x * (1/2)
x = 3(y-1)
------------
If, x = 3(y-1),
-7 * 3(y-1) + 8y = -5
-21 * (y-1) + 8y = -5
-21y + 21 + 8y = -5
21 + 5 = 21y - 8y
26 = 13y
y = 26/13
Therefore: y=2.
----------
If y=2,
x = 3(2-1) = 3

Answers:
x=3 and y=2.
Answer:
Rhombus
Step-by-step explanation:
If a parallelogram has diagonals that are perpendicular, it is a rhombus. A square is a parallelogram with four congruent sides and four right angles. This definition can also be stated as: A square is a quadrilateral that is also a rectangle and a rhombus.
Answer:
50,000
Step-by-step explanation:
1st car had $1,750 tax
2nd car has $3,500 tax
1750(2) = 3500
so your tax doubled so the price must be doubled.
The car is $50,000
Algebraically using direct variation:
t = kp where t=tax, p = purchase price,
and k is constant of variation
1750 = 25000k
k = 1750/25000
k = 0.07
Your equation is: t = 0.07p
3500 = 0.07p
p = 3500/0.07
p = $50,000
The answer is 8
First you do what's in parentheses and that's 6 times 2 which equals 12
The you subtract by 4 which is 8
