Find 4 consecutive even integers such that when three times the smallest of the intagers is added to twice the largest their sum
zhannawk [14.2K]
If x is the first of the integers then the statement is:

(x) , (x+2) , (x+4) , (x+6)

This means that the smallest is x and the largest is x + 6

so:
3(x) + 2(x+6) = 293
3x + 2x + 12 = 293
5x = 281
x = 56.2
This gives us a none integer (decimal)
What now?

Wait remember how x started as the lowest? what if x was the highest instead?

x, x-2, x-4, x-6
so:

3(x-6) + 2(x) = 293
5x = 315
x = 62.2

This is as close as have gotten to the answer
Cant seem to get an integer.
Maybe error in the question or some bad math on my part.

Solve the equation 24+0.44x=19+1.69x
vichka [17]

Answer: X= 4

Step-by-step explanation:

24+0.44x=19+1.69x exp equation like:

24+44x/100=19+169x/100

Multiply left and right side of equation with 100

2400+44x=1900+169x

2400-1900=169x-44x

500=125x

x=500/125

x=4
