We can easily find this using equations.  what do we know?

X + Y = 20  and
-(X - Y = 14)        subtract the two equations..

X + Y = 20
-X + y = -14

2Y = 6
Y = 3        (our first number)  (put this into an original equation and solve)

X + Y = 20
X + 3 = 20    subtract 3 from both sides
X = 17

gives us our answer ....... 3 and 17

Find the product (4x-3) (3x+8)
m_a_m_a [10]

Hi there!

Assuming "Find the product" means multiplying (4x-3) by (3x+8) and factor to it's simplest form the answer would be:

12x²+23x-24

The way you solve this is by using the distributive property of multiplication as shown below:

Start by multiplying -3 from (4x-3) by everything in (3x+8)

3x*(-3) = -9x

8*(-3) = -24

Once you've done that you then multiply everything 4x

4x*8 = 32x

4x*3x = 12x²

(Note: when multiplying two of the same variables like x it means you are multiplying x by itself which is the same as x²)

When you put all of this together it looks like this

12x²+32x-9x-24

from there we combine like terms

32x-9x = 23x

to get

12x²+23x-24

I hope this helps!

God bless,

ASIAX
