7/x+1=2x-1/36 solve for x

x = 11 is the solution of a given algebraic expression

Step-by-step explanation:

Step(i):-

Given

cross multiplication, we get

    7 ( 36) = (2x -1) (x +1)

   252    =  2 x ( x +1) -1( x+1)

  252    = 2 x² + 2x - x -1

  252    = 2 x² + x -1

  2 x² + x -1 = 252

  2 x² + x  = 252 +1

  2 x² + x - 253 = 0

Step(ii):-

The factors of 2 x² + x - 253 = 0

  2 x² + 23 x - 22x - 253 =0

  x ( 2x + 23) - 11 ( 2x +23 ) =0

  ( x -11) ( 2x + 23) =0

  x = 11  ,  x =

Final -

The value of x = 11

the thermometer is precise but not accurate

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
