Answer:

  8 = 3x - 4y

or  y = (3/4)x - 2

Step-by-step explanation:

(4,1)  and (0, -2)  are the two points I see.

slope =  (1 -(-2))/(4 - 0) =  3/4

y-int:  -2

y = (3/4)x - 2

or   2 =  (3/4)x - y

  8 = 3x - 4y

Answer:

x = 5

Step-by-step explanation:

4x + 2y + z = 24

2x - 3y - z = 2

5x + y + 2z = 21

-----------------

Eliminate z

Add the 1st and 2nd eqn

4x + 2y + z = 24

2x - 3y - z = 2

----------------

6x - 1y = 26 eqn A

Multiply the 2nd eqn by 2, then add the 3rd.

4x - 6y -2z = 4

5x + y + 2z = 21

----------------

9x - 5y = 25 eqn B

---------------

Now you have 2 eqns in 2 unknowns, not 3.

Multiply eqn A by 5 and subtract eqn B.

30x - 5y = 130 eqn A times 5

9x - 5y = 25 eqn B

-------------

21x = 105

x = 5

Answer:

x = 31°

Step-by-step explanation:

\triangle ABC \cong \triangle DCE... (given) \\\\\therefore m\angle B = m\angle E..(cact)\\\\\because m\angle B = 61\degree \\\\\therefore m\angle E = 61\degree \\\\In \: \triangle DCE\\\\m\angle D+ m\angle C + m\angle E = 180\degree \\(by \:  interior \:  angle  \: sum \:  property \:  of \:  a triangle) \\\\2x\degree + 57\degree + 61\degree= 180\degree \\\\2x\degree + 118\degree = 180\degree \\\\2x\degree = 180\degree - 118\degree  \\\\2x\degree = 62\degree  \\\\x = \frac{62\degree}{2} \\\\x = 31\degree
