Answer:
x=0;y=-2
Step-by-step explanation:
multiply first equation by 6: 18x-24y=48
Subtract 2nd equation from 1st: -19y=38
y=-2
Sub into 1st equation: 3x-4(-2)=8
3x+8=8
3x=0
Therefore, x=0;y=-2
S and N are the variables
Answer: 45 kilometers
Step-by-step explanation:
The equation to solve this problem is:
$165 = 1.4x + 102
The variable x represents the number of kilometers he travels.
To solve the equation:
Subtract 102 from each side-
63 = 1.4x
Next divide each side by 1.4-
45 = x
