How do you solve k-19 equals 78?

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)...

H=-31.2 You know H is a larger neg number because answer is still negative-you simply add the last 2 nos. make it negative then subtract 7.8 to check your answer.

If T2 = 78, then T = 78(1/2) or the square root of 78, or about 8.83.

121 is the answer

6y - 5 = -5; so 6y = -5 + 5; so 6y = 0; so y = 0
