X+2y=1
2y =1-x
y= (1-x)/2
5x-4y= -23
By substituting the value of y in this equation
5x -4 {(1-2)/2} = -23
5x- 2 +2x = -23
7x= -21
x= -3
Now, let's find the value of y bu putting the value in any othe two equations
I'll use x +2y=1
-3 +2y=1
2y =4
y=2
So, the value of x and y is -3 and 2 respectively.
Answer: 10a, all of the numbers can be divided by 10a

Answer:
x = 31 and y = 2
Step-by-step explanation:
Parallelogram
4x + 2x - 6 = 180
6x = 186
x = 31
5y = y + 8
4x = 8
y = 2
answer
x = 31 and y = 2
