Simple....
you have: 4(x+7)
To simplify it..distribute..
4(x+7)
4*x=4x
and
4*7=28
Leaving you with...
4x+28
As we can see B is 4x+28
Thus, your answer.
-4x + 2y = -6
2y = 4x - 6
y = 2x - 3....y int = -3 , x int = (3/2,0)
I believe it is going to be : -4x + 2y = -6
If you would like to find the solution of the system of equations, you can do this using the following steps:
x - 8y = 21 /*(-3)
3x - 8y = 15
______________
-3x + 24y = -63
<span>3x - 8y = 15
</span>______________
-3x + 24y + 3x - 8y = -63 + 15
16y = -48 /16
y = -48/16
y = -3
<span>x - 8y = 21
</span>x = 21 + 8y
x = 21 + 8 * (-3)
x = 21 - 24
x = -3
(x, y) = (-3, -3)
The correct result would be (-3, -3).
I'm going to take a guess and say 60, and the reason I say 60 is because I just thought 180 / 60 LOL
D - gasoline number of miles you drove since filling up
