Solve for x<br><br>-3(-3x-1) +2x+2=27​
Zielflug [23.3K]

Answer:

x=2

Step-by-step explanation:

So we have the equation:

-3(-3x-1)+2x+2=27

First, distribute the -3:

9x+3+2x+2=27

Combine like terms:

11x+5=27

Subtract 5 from both sides:

11x=22

Divide both sides by 11:

x=2

So, the value of x is 2.

And we're done!

<em>I'm fairly certain it should be as y decreases x will increase. </em>

As your y value moves along the graph to the right the x is getting larger and inversely as it moves to the left the x value gets smaller (negative). Y is not increasing as x increases.
