Answer:A quick way to solve this problem involves copying the given equation:
2x + 5y = 10
dropping the final 10, and
substituting the given x and y values: (5, -4).
Then:
2(5) + 5(-4) = C C = 10-20 = -10
Thus, the equation of this new, parallel line is 2x + 5y = -10.

Answer:
dividing by a fraction is multiplying by the reciprocal.
This example swaps the left hand in stead of the right hand.
So the correct approach would have been:
x = 5
18x-30-7x = 25
11x = 55
x = 55/11
x=5
