2x+3y=11 5x+3y=23 cara metode eliminasi dan cara metode eliminasi&substitusi

eliminasi

2x + 3y = 11
5x + 3y = 23 -
--------------------
-3x = -12
3x = 12
x = 12/3
x = 4

2x + 3y = 11 | x5
5x + 3y = 23 | x2

10x + 15y = 55
10x + 6y = 46 -
-----------------------
9y = 9
y = 9/9
y = 1

X = 4 ; Y = 1

Eliminasi & Substitusi

2x + 3y = 11
5x + 3y = 23 -
--------------------
-3x = -12
3x = 12
x = 12/3
x = 4

2 . (4) + 3y = 11
8 + 3y = 11
3y = 11-8
3y = 3
y = 3/3
y = 1

X=4 ; Y= 1

HP = {4,1}


maaf kalo salah:(
semoga membantu:)

metode eleminasi&subtitusi
2x + 3y = 11 |×5|
5x + 3y = 23 |×2|

10x + 15y = 55
10x + 6y = 46
• 9y=9
• y= 1

• 2x +3(1) = 11
• 2x = 11-3
• x= 8/2 = 4

metode eleminasi
2x + 3y = 11
5x + 3y = 23
------------------- -
-3x=-12
x= 4

•2(4) + 3y = 11
•3y=11-8
•y=3/3 = 1
