Answer: 92 and 94
Step-by-step explanation:
x = first number
x + 2 = second number
x + x + 2 = 186
simplify
2x + 2 = 186
subtract 2 from both sides
2x = 184
divide both sides by 2
x = 92
92 + 2 = 94
The numbers are 92 and 94.
Answer:
105 is your answer
Step-by-step explanation:
Let the two consecutive integers be: x , x + 1
Set the equation
x + x + 1 = 209
Simplify. Combine like terms.
(x + x) + 1 = 209
2x + 1 = 209
Isolate the x. Note the equal sign, what you do to one side, you do to the other.
Subtract 1 from both sides
2x + 1 (-1) = 209 (-1)
2x = 209 - 1
2x = 208
Isolate the x. Divide 2 from both sides
(2x)/2 = (208)/2
x = 208/2
x = 104
------------------------------------------------------------------------------------------------------
Plug in 104 for x.
(x + 1) = (104) + 1 = 105
105 is your answer
