35. 3x-2y=12. x5. = 15x-10y =60
5x+y =7. x3. = 15x+3y. =21
------------------------------------------------ -
= - -13y=39
,y=39:-13=-3
3x-2y=12=3x-2(-3)=12=3x+6=12
3x=12-6. =3x=6. x=6:3=2
x=p=2. y=q=-3
jd 8p-2q=8(2)-2(-3)=16+6=22
36. x+y=75. x4. =4x+4y=300
4x+2y=210. x1. =4x+2y=210
------------------------------------------------- -
=- +2y=90
y= 90:2=45(motor)
x+y=75. = x+45=75. x=75-45=30(mobil)
uang parkir yg d trm=45x2000=90000
