Answer:
x = -1 y = -1
Step-by-step explanation:
x + 3y = −4
x + 5y = −6
Multiply the first equation by -1
-x - 3y = 4
The add to the second equation to eliminate x
-x - 3y = 4
x + 5y = −6
--------------------
2y = -2
Divide by 2
2y/2 = -2/2
y = -1
Now solve for x
x+3y = -4
x +3(-1) = -4
x -3 = -4
Add 3 to each side
x-3+3 = -4+3
x = -1
Answer:
Your answer is <em>6x</em>
Step-by-step explanation:
Given,
length(l) = 3x
breadth(b) = 2x
area of a rectangle(A) = ?
Now,
A = l*b
A = 3x*2x
A = 6x ans.

Answer:
sum of exterior angles of polygon = 360°
therefore,
z = 360 - (105+145)
z = 360 - 250
z = 110°
5/4
as 1.00/0.80 = 100/80
and then when you simplify it the answer would be 4/5.
