Accepted Solution
A:
Answer:The Answer is: The first number is -70 and the second number is -68.Step-by-step explanation:Let f = first number and s = second number.The sum of both is -138:f + s = -138The difference is -2f - s = -2Solve for f:f = -2 + sf = s - 2Substitute:s - 2 + s = -1382s = -136s = -68, the second numberSolve for f:f = s - 2f = -68 - 2 = -70, the first numberProof: f + s = -138-68 + (-70) = -138-138 = -138Then: f - s = -2-70 - (-68) = -2-70 + 68 = -2-2 = -2Hope this helps!
