Answer:
b = -10.5, a = 3.5
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Find the two numbers their sum is -7 and their difference is 14.
a + b = -7
a - b = 14
<u>Step 2: Solve for a in the first equation</u>
a + b - b = -7 - b
a = -7 - b
<u>Step 3: Find the b in the second equation</u>
a - b = 14
(-7 - b) - b = 14
-7 - 2b + 7 = 14 + 7
-2b / -2 = 21 / -2
<em>b = -10.5</em>
<em />
<u>Step 4: Substitute into a</u>
a = -7 - b
a = -7 - (-10.5)
a = -7 + 10.5
<em>a = 3.5</em>
<em />
Answer: b = -10.5, a = 3.5
