13-4x=1-x
First,I would move my x's to the right and my numbers to the left so...

13-4x=1-x
   +4x   +4x
-------------------
13=1+3x
-1   -1
----------------
12=3x 

Now, you would divide 3 from both sides.

12=3x
---- ----
3     3
Solution: 4=x

To check the solution, plug in 4 for x.
13-4(4)=1-4
13-16=-3
-3=-3

The  solution works, therefore
x=4

Add 4x to both sides and get
13 = 1 + 3x
12 = 3x   [from subtracted 1 from both sides]
x = 4      [from dividing 3 from both sides]

therefore your answer would be  x = 4

Please I need Help Im confused
vitfil [10]

Answer:

<em>x</em><em>=</em><em>3</em><em>.</em><em>5</em><em> </em><em>y</em><em>=</em><em>8</em>

Step-by-step explanation:

Remeber, in a rectangle, opposite sides are equal so

2x + 3y = 31

and

a

2x + 1 = y

Subsitue 2x+1 for y.

2x + 3(2x + 1) = 31

2x + 6x + 3 = 31

8x + 3 = 31

8x = 28

x = 3.5

Plug this back in to one of the equations to find y.

2x + 1 = y

2(3.5) + 1 = y

7 + 1 = y

8 = y

So x=3.5

y=8
