jawabnya apa ya kak? jangan lupa pake cara

::: 1/3(x+3) + 1/2(y-2) =2 |×6
2(x+3) + 3(y-2) = 2×6
2x +6 +3y -6 = 12
2x +3y =12 ....... pers1
:::: 1/3(2x+3) - 1/5(y+2)=-5 |× 15
5(2x+3) -3(y+2) = -75
10x +15 -3y-6= -75
10x -3y = -75 -15 +6
10x -3y =-84....... pers 2
eliminasi pers 1 dan 2
2x +3y =12
10x -3y = -84 +
_____________
12x =-72
x = -72/12
x = -6
::;:substitusi ke pers 1
2x +3y = 12
2(-6) +3y =12
-12 +3y =12
3y =12+12
y =24/3
y =8

x +3y = -6 + 3(8)
= -6 + 24
