When its gets closer, it gets larger
<span>Amanda has 26 nickels and dimes.
We shall call nickels x and dimes y.
We can write the following equations:
x = 3y -2 or -x +3y = 2
x + y = 26
We can cancel out the x to give 4y = 28 or y = 7
If there are 26 coins in total and 7 of them are dimes then there must be 19 nickels.
The number of nickels (19) is two fewer than three times the number of dimes ( 3(7) - 2 = 19).</span>
If your looking for the x and y-int
For f(x)=3x+7 it would be
X-int: (-7/3,0)
Y-int: (0,7)
For 2f(7)-3
So if you simply you would get 14f-3
Hope this helps you!! Have a great day!
If something is wrong let me know please
Hello:
(3/4)x-3 = (1/2)x+2
(3x-12)/4 =(2x+8)/4
3x-12 = 2x+8
3x-2x = 12+8
x =20
