Answer:

$3\neq -3$

False

Step-by-step explanation:

$y=3x-9\\\\x-\frac{1}{3}y=-3$

You substitute $y$ for the second equation.

$x-\frac{1}{3} y=-3\\\\x-\frac{1}{3}(3x-9)=-3$

Then you have to distribute $-\frac{1}{3}$ .

$x-x+3=-3$

Combine like terms.

$3\neq -3$

Answer:

<h2>X=6</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>let's solve:</h3>

$\sf cancel \: 4 \: from \: both \: sides : \\ \sf \implies \: 3x + 4 - 4 = 22 - 4 \\ \implies \sf \: 3x = 18$
$\sf divide \: both \: sides \: by \: 3 : \\ \sf \bcancel \frac{3x}{3} = \frac{ \cancel{18} \: \: ^{6} }{ \cancel{ \: 3}} \\ \therefore \rm \: x = 6$

Can someone please explain to me how to find the answer 7+ 4x + 5x

Since you have two numbers that have a (x) at the ends of them, you add those first then add seven which will end up being 9x+7
