Answer:
Kim is 3, Tom is 12
Step-by-step explanation:
4x + x = 15
combine like terms
5x = 15
divide both sides by five
x = 3
Answer:
-15 and -13
Step-by-step explanation:
Assume that x is an odd integer, if we added one to this integer it would become even and then if we added one again it would become odd again. With this said
x --> first odd integer
x + 2 --> second odd integer
We want these integers to equal -28 so:
x + (x + 2) = -28
2x + 2 = -28
2x = -30
x = -15
Then we plug in x back into (x+2) to get the second integer
-15 + 2 = -13
And to check
-15 + -13 = -28
