Need with following questions

2x+5=2x-4

2x+6=15x-7

2x+6=8+2x

x+2y=5=x+3y=8

a) no solution; b) x = 1; c)  no solution; d) no solution

Step-by-step explanation:

Next time, please be more specific regarding what kind of help you want.  In this case, it'd be "Solve for x."

2x+5=2x-4 has the term 2x on both sides; we can eliminate this by subtracting 2x from both sides.  But this leads to 5 = -4, which is never true.  This equation has no solution.

2x+6=15x-7 can be rewritten as 13 = 13x.  Dividing both sides by 13, we get x = 1.  The solution is x = 1.

2x+6=8+2x is similar to 2x+5=2x-4 in that both sides have the "2x" term, and 6≠8.  No solution.

x+2y=5=x+3y=8 has two variables (x and y).  

Subtracting 2y from both sides results in:   x = 5 = x+y = 8.  This is not possible, because it states that 5 = 8.  No solution (or possible mistake in copying down this problem).

step-by-step explanation:

answer: e 9, 5.75

step-by-step explanation:

step 1

find the variation ab in the x coordinate

delta x=(x2-x1)=10-> 8 units

find the variation ab  in the y coordinate 

delta y=(y2-y1)=6-> 2 units

step 2

find the coordinates point c

  x coordinate 

cx=ax+delta x*2/> cx=2+8*(2/> cx=3

  y coordinate 

cy=ay+delta y*2/> cy=4+2*(2/> cy=4.25

the coordinates of point c are (3,4.25)

step 3

find the coordinates point d

  x  coordinate 

dx=ax+delta x*4/> dx=2+8*(4/> dx=4

  y  coordinate 

dy=ay+delta y*4/> dy=4+2*(4/> dy=4.5

the coordinates of point d are (4, 4.5)

step 4

find the coordinates point e

  x  coordinate 

ex=ax+delta x*4/> ex=2+8*(6/> ex=5

  y  coordinate 

ey=ay+delta y*4/> ey=4+2*(6/> ey=4.75

the coordinates of point e are (5, 4.75)

step 5

find the coordinates point f

  x  coordinate 

fx=ax+delta x*4/> fx=2+8*(8/> fx=6

  y  coordinate 

fy=ay+delta y*4/> fy=4+2*(8/> fy=5

the coordinates of point f are (6,5)

step 6

find the coordinates point g

  x  coordinate 

gx=ax+delta x*4/> gx=2+8*(10/> gx=7

  y  coordinate 

gy=ay+delta y*4/> gy=4+2*(10/> gy=5.25

the coordinates of point g are (7,5.25)

step 7

find the coordinates point h

  x  coordinate 

hx=ax+delta x*4/> hx=2+8*(12/> hx=8

  y  coordinate 

hy=ay+delta y*4/> hy=4+2*(12/> hy=5.5

the coordinates of point h are (8,5.5)

step 8

find the coordinates point i

  x  coordinate 

ix=ax+delta x*4/> ix=2+8*(14/> ix=9

  y  coordinate 

iy=ay+delta y*4/> iy=4+2*(14/> iy=5.75

the coordinates of point i are (9,5.75)
