Question

find the equation whose sum is 16 and difference is 18​

Answer 1

Answer:

first number is 17 and other number is -1

Answer 2

Step-by-step explanation:

The sum of x and y is 16. In other words, x plus y equals 16 and can be written as equation A:

x + y = 16

The difference between x and y is 18. In other words, x minus y equals 18 and can be written as equation B:

x - y = 18

Now solve equation B for x to get the revised equation B:

x - y = 18

x = 18 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 16

18 + y + y = 16

18 + 2y = 16

2y = -2

y = -1

Now we know y is -1. Which means that we can substitute y for -1 in equation A and solve for x:

x + y = 16

x + -1 = 16

X = 17
