Answer:
The first number is −13 and the second number is −6
Step-by-step explanation:
The first number is −13 and the second number is −6
Explanation:
Let's let the first number be n and the second number be called m.
Then, from the first sentence we can write:
n = m − 7
and from the second sentence we can write:
2n = 6m + 10
Substitute m − 7 for n in the second equation and solve for m:
2(m − 7) = 6m + 10
2m − 14 = 6m + 10
2m − 14 − 2m − 10 = 6m + 10 − 2m − 10
−14 −10 = 6m −2m
−24 = 4m
-24/4 = 4m/4
m= −6
Now substitute −6 for m in the first equation and calculate n:
n = −6 −7
n = -13
