Question

1. x- 2y = 4
-4y = -2x+8

2. x+y=7
2x+3y =20

3. 3x-2y=6
x+2y= 10

4. 6x-y=3
4x+2y=10

5. 2x-y=8
3(x-1)+(y-1)= 18

6. 3(x+y) -2(x+2y) =2
4(2x-3y) -3(x-y)= 6

7. x/4 +y/4 = 2
x/6 - 2 = - y/3

8. ½x - ⅓ y = 1
¼x + ½ y = 2½

9. x+4/2 + y-4/3 = ½
-2 (y+x) +1=1

10. x+2/4 - 3-y/3 = -¼
x+y = 0

11. (x+1)² + y²-8 = (y-2)²+ (x-3)(x+3)
3x-y+4=0

12. (x-2)(x+2)+2y= (x-2)²+y
3x+2y=11

13. 4(x-1)+6 = 2-2(1-y)
3(x-y)+2=x-3(y-2)

14. (x+1)²+(y-1)²p= (y-3)²+(x-3)(x+3)
3x-y+3=0

15. (x-3)²- (x+5)(x-5)=2y + 48
x+y/2 - x-y/4 =¾
