How do you solve 14x-2y equals 78 2x-2y equals 6?

Answer 1

are those two different problems ? ... i am going to solve them as if they are

14x-2y=78

(re arange the terms to be easily solved)

-2y=78-14x

(times by -1)

2y= -78+14x

(divide all terms by 2)

y=-39+7x

(so)

y=7x-39

2x-2y=6

(re arange the terms to be easily solved)

-2y=6-2x

(times by -1)

2y=2x-6

(divide all terms by 2)

y=x-6
