<h3>Answer:</h3>

$\large\boxed{x=-6}$

<h3>Step-by-step explanation:</h3>

In this question, we have to solve the equation.

We would do this by combining like terms and solving after that.

Solve:

$\frac{2}{3}x - 9 - 2x + 2 = 1\\\\\text{First add two to -9}\\\\\frac{2}{3}x - 2x -7 = 1\\\\\text{Add 7 on both sides}\\\\\frac{2}{3}x - 2x = 8\\\\\text{Multiply everythhing by 3}\\\\2x-6x=24\\\\\text{Combine the x terms}\\\\-4x=24\\\\\text{Divide by -4}\\\\x=-6$

Your answer would be x = -6

2x+3y=1 and y=-2 - 9 solve using linear combination method. Please explain steps.

Answer:

$x=17$

Step-by-step explanation:

$2x+3y=1$

$y=-2-9$

In order to combine these two equations, an idea you need to keep in mind is finding a way of setting these equations as equal to each other. I saw that each equation shared a common value, $y$ . In this case, we need to isolate $y$ in the first equation so that both equations $=y$ .

$2x+3y=1$

$3y=-2x+1$

$\frac{3y}{3}=\frac{-2x+1}{3}$

$y=-\frac{2}{3}x+\frac{1}{3}$

With this, we now know that both $-2-9$ and $-\frac{2}{3}x+\frac{1}{3}$ are equal to $y$ , so we can set them equal to each other.

$y=-\frac{2}{3}x+\frac{1}{3}$

$y=-11$

$-\frac{2}{3}x+\frac{1}{3}=-11$

Reply to this if anything I'm saying or doing is confusing in any way, or if you find a mistake. :) Solve for $x$ .

$-\frac{2}{3}x+\frac{1}{3}=-11$

$-\frac{2}{3}x=-11-\frac{1}{3}$

$-\frac{2}{3}x =-\frac{33}{3}-\frac{1}{3}$

$-\frac{2}{3}x =-\frac{34}{3}$

$-\frac{2}{3}x(-\frac{3}{2})=-\frac{34}{3}(-\frac{3}{2})$

$x=\frac{102}{6}=17$

$x=17$

Hopefully this answer is correct AND makes sense in terms of how I achieved it. Again, reply to this with any questions or mistakes I made and I'll do my best to answer or fix them.
