Find the two numbers their sum is -7 and their difference is 14.

b = -10.5, a = 3.5

Step-by-step explanation:

Step 1:  Convert words into an expression

Find the two numbers their sum is -7 and their difference is 14.

a + b = -7

a - b = 14

Step 2:  Solve for a in the first equation

a + b - b = -7 - b

a = -7 - b

Step 3:  Find the b in the second equation

a - b = 14

(-7 - b) - b = 14

-7 - 2b + 7 = 14 + 7

-2b / -2 = 21 / -2

b = -10.5

Step 4:  Substitute into a

a = -7 - b

a = -7 - (-10.5)

a = -7 + 10.5

a = 3.5

 b = -10.5, a = 3.5
