Question

Solve
-6=3x-6y
4x=4+5y for x and y or no solution and infinite

Answer 1

3 -6 | -6 1 -2 | -2 (4)
-4 5 |-4


4 -8 | -8
-4 5 |-4
---------
-3|-12
1|4 ; y = 4

Answer 2

6,4

Answer 3

1 -2 | -2
0 1 | 4 (2)


1 -2 | -2
0 2 | 8
---------
1 0 | 6 ; x = 6

Answer 4

oh look it is (6,4) again!

Answer 5

4x -5y= 4
-3x+6y = 6
12 x- 15y = 12
-12x +24y = 24
9y = 36
y = 4
x = 4 +20 / 4
x = 24 /4 = 6

Answer 6

6 and 4 are transcendant numbers lol

Answer 7

u r too fast for me amis!!

Answer 14

gian isn't giving up!!

Answer 15

-6=3x-6y this can be written 6y = 3x + 6 (divide by 6) y = 1/2x +1
4 x=4+5y (substitute above value of y into this equation)
4x = 4 + 5(1/2x +1) expand brackets now
4x = 4 + 5/2x + 5 (subtract 5/2x from both sides and simplify RHS
3/2x = 9
multiply by 2 on both sides
3x = 18 now divide by 3 on both sides
x = 6
Now sub this value of x into equation 1
-6 = 3(6) - 6y
-6 = 18 - 6y
now -6 -18 = -6y
-24 = -6y
y = 4
Phew we got there!

Answer 16

well done
