Hello
3x - 5y = 21
2x + y = 1
We need to solve 2x+y=1 for y
So now we have, y = -2x +1
Substitute -2x +1 for y in 3x-5y = 21
3x - 5y = 21
3x -5 (-2x+1)=21
3x + 10x -5= 21
13x -5 = 21
13x = 21+5
13x = 26
x= 26/13
x= 2
Now we have the value of x, with that we can find the value for y
let's do that by substitute 2 for x in y = -2x +1
y = -2x +1
y= -2(2) +1
y= -4 +1
y= -3
Final answer : Y= -3 and x= 2
I hope that's help !
Answer:
7 miles
Step-by-step explanation:
If there is a $2.50 fix charge, that means you will have to pay $2.50 no matter how many miles you go. So automatically, subtract $2.50 from the $20 that you have, which will now be $17.50 left.
Now for every mile its $2.50 charged. So $2.50 for one mile, $5 for two miles $7.50 for 3miles, $10..$12.5...keep adding $2.50 untill you get to the maximum amount $17.50. You will discover that you added 2.50 7 times until you got 17.50 So you can only go 7 miles. Or to do it even quicker just divide 17.5/2.50=7
