24 miles is 1 gallon so 360 miles is 15 gallons + 24 is 384 miles so they are not equivalent!
Answer:
{x,y} = {5,6}
Step-by-step explanation:
// Solve equation [1] for the variable x
[1] x = y - 1
// Plug this in for variable x in equation [2]
[2] 2•(y -1) - y = 4
[2] y = 6
// Solve equation [2] for the variable y
[2] y = 6
// By now we know this much :
x = y-1
y = 6
// Use the y value to solve for x
x = (6)-1 = 5
For this one your answer is -309
It would be a > 12, move all terms to one side and then solve for x. make sure if you divide then you flip the term
