The product of 32 and an unknown number subtracted from 435 is 179 what is the value of the unknown number

Hello from MrBillDoesMath!

  Case 1: approximately   429.4, Case 2: 8

Discussion:

Let the unknown be "x". The problem statement could mean either

32 * (435 -x)  = 179     (#1)

or

435 - 32*x = 179             (#2)

It's unclear which one is wanted so we solve both of them.

#1

But for case #1

32 * (435 -x)  = 179  

32 * 435 - 32x = 179   or

13920 - 32x = 179

Add 32x to both sides

13920 = 179 + 32x

Subtract 179 from both sides:

13920 - 179 = 32x

Divide both side by x to get

x = (13920 -179)/32 =  13741/32 which is approximately   429.4

For case #2

#2

435 - 32x = 179.  Add 32 x to each side

435 -32x + 32x = 179 + 32x. Subtract 170 from each side

435 -179 = 32x or

32x = 256   or x = 8

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

2x^2+5x+17

your welcome. : )
