This is a little bit weird, but it's not hard if you just
do it one step at a time.

Here's the important part that you need to know
in order to solve this problem:

    All four sides of a square are equal.

Got that ?   Good.
Here we go.

-- First, take the left and right sides.
   They must be equal, so

   2y - 5 = y - 1

Add 5 to each side:    2y   = y + 4

Subtract 'y' from each side:    y = 4 .

The left side is y-1 = 3

The right side is     2y-5 = 2(4) - 5
          = 8 - 5
          =    3 .

Good ! We have the left and right sides equal.
Do we really need to do the other two sides ?
They told us it's a square, so can't we just say
   the top and bottom are also 3 ?
Well, maybe. But maybe they're trying to trick us,
   and the top and bottom aren't really 3 . I think
   we ought to check it out. It's more good math practice.

-- Take the bottom side ... it's 3y-9 .

But you know what 'y' is !
We just calculated that y=4,
so
   3y - 9 = 3(4) - 9 = 12 - 9 = 3 .

Great ! The bottom side is 3 .

Answer:

x=30⁰

Step-by-step explanation:

4x-55+3x+25=180

7x-30=180

7x=210

x=30⁰

Proof

3(30)+25=115

4(30)-55=65

115+65=180⁰

3. 11x-7y=-14. X-2y=-4

Answers

11x -7y= -14 (1)
x -2y= -4 (2)

Multiply (2) by 11, we have:
11x -22y= -44 (3)

Take (1)-(3), we have:
(11x-11x)+ (-7y-(-22y))= -14-(-44)
⇒ -7y+22y= -14+44
⇒ 15y= 30
⇒ y= 30/15
⇒ y= 2

x= -4+ 2y= -4+ 2*2= 0

The final answer is x=0, y=2~

The two given equations are
11x - 7y = - 14
x - 2y = -4
Now let us take the second equation for finding the value of x first
x - 2y = -4
x = 2y - 4
Now we have to put the value of x in the first equation
11x - 7y = - 14
11(2y - 4) - 7y = -14
22y - 44 - 7y = -14
15y = 44 - 14
15y = 30
y = 30/15
= 2
Now let us put the value of y in the second equation
x - 2y = -4
x - 2(2) = -4
x - 4 = -4
x = -4 + 4
= 0
So the value of x is 0 and the value of y is 2.
