Solve and show your work.<br><br> 1. 3(2x + 3) - 4x = -3<br><br> 2. 26 = 3x - 2 - 7x
yKpoI14uk [10]

Answer:

1. x=-6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(2x+3)−4x=−3

(3)(2x)+(3)(3)+−4x=−3(Distribute)

6x+9+−4x=−3

(6x+−4x)+(9)=−3(Combine Like Terms)

2x+9=−3

2x+9=−3

Step 2: Subtract 9 from both sides.

2x+9−9=−3−9

2x=−12

Step 3: Divide both sides by 2.

x=-6

What is the domain of the functions below: b y= 5x/|x−1| −1
sdas [7]

Answer:

<h2>DOMAIN: The set of all real numbers except 0</h2>

\large\boxed{x\in\mathbb{R}-\{0\}}

Step-by-step explanation:

We have a faction.

We know: the denominator must be different from 0. Therefore

y=\dfrac{5x}{|x-1|}-1\Rightarrow |x-1|\neq0\iff x-1\neq0\iff x\neq1
