To find the value of x let's make the situation a bit easier

3x+10+70=180
3x+80=180
3x=180-80
3x=100
x = about 33.33

$3x + 10 + 70 = 180 \\ 3x + 80 = 180 \\ 3x = 180 - 80 \\ 3x = 100 \\ x = \frac{100}{3} \\ x = 33.33$

Hope this helps!

The smallest of three consecutive integers is 24 less than the sum of the two larger integers. Find the three integers.

harkovskaia [24]

Answer:

21, 22, 23

Step-by-step explanation:

Construct equations representing each piece of information.

Three consecutive integers are three numbers in a row, for example, 1, 2 and 3.

Let's let

Integer 1 = X

Integer 2 = Y

Integer 3 = Z

X = (Y + Z) - 24

We also know that

Y = X + 1

and Z = X + 2

We can now sub this information into the first equation. We do this so that we can have only one variable in the equation.

X = (X+1) + (X+2) - 24

now solve for x,

X = 2X + 3 - 24

X = 2X - 21

-X = - 21

X = 21

So, the integers are 21, 22, 23
