3 times 7= 21 times three =63
K=8k+28
subtract 8k from both side
-7k = 28
divide both side by -7
k= -4
Regular= 3/5 equivalent= 6/10 just multiply the top and bottom by the same number.
Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
x + y = 3
x = 3 - y
y = 2x - 15
y = 2(3 - y) - 15
y = 6 - 2y - 15
y = -2y - 9
3y = -9
y = -3
y = 2x - 15
-3 = 2x - 15
-2x = -12
x = 6
So...
The answer is: (6, -3)
Answer:
No
