Question

13. Choose the ordered pair that is the solution to the system of equations.

-5y + 4x = 8

-15y + 3x = -3




(3,4/5)

(-3,-4)

(-3,4/3)

(3,0)

Answer 1

-5y + 4x = 8 (e shumezojme me 3)----->-15y+12x=24 (i zbresim ane per ane)
-15y + 3x = -3 -15y+3x=-3
9x=27
x=27/9=3
y---> -5y+12=8
-5y=-4
y=4/5
zgjidhja eshte (3;4/5)

Answer 2

15y-12x=-24
-15y+3x=-3
=>-9x=-27 => x=3
y= 4/5

Answer 3

E kape?

yw :)

Answer 6

15. Choose the ordered pair that represents the solution to the system of equations.

x + y = 4

y = 2x + 1

(1,3)

(-1,3)

(1,-3)

(-1,-3)

Answer 7

x+y=4
-y+2x=-1
=>3x=3 => x=1
y=3

Answer 8

(1;3)
x + y = 4 --->x+y=4(shumezojme me 2)---->2x+2y=8 (mbeldhim ane per ane)
y = 2x + 1 y-2x=1 y-2x=1
3y=9
y=3
x+3=4
x=1

Answer 9

system:
-5y + 4x = 8
-15y + 3x = -3
equal:
(3, 4/5)
