The answer is 3 equation is 3x-3=2x
The first statement says that the number tripled is 3 more then when it’s doubled. It means that 2x which is being doubled is equal to 3x-3.
You set it up as 3x-3=2x
To solve you subtract the 2x from both side and end up with x-3=0
And then you have to add 3 to both side to get the answer x=3

<u>Let's take this problem step by step:</u>

<u>To find the ordered pair of the system:</u>

⇒ must set both equations equal to each other

⇒ and solve for 'x'

<u>Let's solve:</u>

$x^2-2x+3=-2x+19\\x^2-2x+2x+3-19=0\\x^2-16=0\\(x+4)(x-4)=0$

<u>Let's find the x-values:</u>

$(x-4)=0\\x=4\\\\(x+4)=0\\x=-4$

<u>Let's find f(x)'s value for each 'x':</u>

$x=4\\f(4)=-2(4)+19=-8+19=11\\\\x=-4\\f(-4)=-2(-4)+19=8+19=27$

<u>Answer: (4, 11), (-4,27)</u>

Hope that helps!
