Answer:
73, 74, 75
Step-by-step explanation:
So the sum of three consecutive integers is 222.
Let's let the first integer be n.
Then the second integer <em>must</em> be (n+1).
And the third integer must be (n+2).
They total 222, thus:
Combine like terms:
Subtract 3 from both sides:
Divide both sides by 3:
So, the first integer is 73.
So our sequence is 73, 74, and 75.
And we're done!
Answer:
5x=2x−4−2
Subtract 2 from −4 to get −6.
5x=2x−6
Subtract 2x from both sides.
5x−2x=−6
Combine 5x and −2x to get 3x.
3x=−6
Divide both sides by 3.
x= -6/3
Divide −6 by 3 to get −2.
x=−2
