Mathematics Task ._.

LINEAR EQUATION WITH TWO VARIABLES

·        Linear equation with two variable is the step to solving problem with step of =

1.     Graphical method

2.     Elimination method and

3.     Substitution method

              

Exercise :

A.    Solving the following simulaneous linear equation in two variables using substitution method!

1.     X=2y

2y-x=3

2.     X-2y=2

x+2y=6

B.     Express the following statement in a linear quation in two variable

1.The perimeter of a rectangle is 84

2.The perimeter of an isosceles triangle is 78

3.     The sum of budi’s and abi’s marble is 24                                                 

=5

C.      Finish the linear equation  with elimination method :

1.     4x+3y=11 and 5x-4y=6

2.     3x-2y=8 and 4x-3y=11

3.     7x-3y=6 and 8x+5y= -1

D.    Finish the linier equation witth substitution method

1.     Y=x+1 and 2x+3y=13

2.     1/2x-1/5 (y-3)=1 and x-y=-1

3.     3x+5y=1 and 1/3 (x-6)-1/2y=0

E.     Mandra bought 5 books and 4 pencils, the price Rp 8.000,00 at Jayo shop. After that Joko bought 3 books and 5 pencils, the price Rp 6.100,00.

1.     create mathematical sentences with linear equation with 2 variable

2.     sum with diagram graphics method

F.     By substitution method , determine whether each of the following ordered pairs is the solution of the simultaneous linear equation

1.     x + 2y = 3

2x=3y = 4

2.     x + y = -5

x - 2y = 4

3.     2x + 3y =8

3x + 2y =17

4.     2x – 3y = -10

x + 2y = 2

5.     Substitution of y = 2 into equation 2x + 3y = 12 : 2x + 3(2) = 12

G.    By elimination

1.     2x – 3y = -10

x + 2y = 2

2.     2x + 3y = 12

4x – 7y = -2

3.     2x + y = -5

3x – 2y = 12

4.     3x + 2y = 12

x + 2y = 6

5.     x + 2y = 6

-x + 2y = 4

Musik (˘⌣˘ʃƪ)

Hai guys, cerita sedikit boleh dong yaa :)

Musik, 5 kata tetapi mengandung banyak arti yang bermanfaat. Musik bisa
membuatmu enjoy dalam menikmati kehidupan. Memang awalnya belajar
untuk bisa memainkan alat musik sulit. Tetapi "kesuksesan bisa kamu raih
jika kamu memang menginginkannya, tekuni dengan kegigihan, laksanakan
dengan penuh usaha" - #TitaQts
