jika 3x-2y =-4 dan 2x-3y=-1 maka nilai dari 2x+3y adalah..... tlong di bantu ya

Jawaban Terlampir....

3x - 2y = -4 [x 2]
2x - 3y = -1 [x 3]

6x - 4y = -8
6x -9y = -3
_________ _
5y = -5
y = 5/-5 = -1

2x - 3y = -1
2x - 3(-1) = -1
2x + 3 = -1
2x = -1 - 3
2x = -4
x =-4/2 = -2

2x + 3y
2(-2) + 3(-1)
-4 - 3 = -7
