diketahui : 3x + 2y = 24 x + 2y = 12 nilai dari 2x + 5y adalah tolong di jawab beserta caranya ya

x+2y= 12
x= 12-2y
3(12-2y) + 2y= 24
36 - 6y + 2y= 24
-6y+2y = 24-36
-4y= -12
y= -12 / -4
y= 3
x = 12 - 2(3)
x= 12-6
x= 6
2x + 5y = 2(6) + 5(3) = 12 + 15 = 27

3x + 2y = 24 | 2 | 6× + 4y= 48
x + 2y = 12 | 2 | 2x+ 4y = 24
4x = 24 jadi x = 6
jadi x + 2y = 12
6 + 2y = 12
2y = 12 -6
y = 3
jadi
2x + 5y = 2(6) + 5(3)
= 27
