Given the equation 7(x + 2) = 2x − 1, solve for the variable. Explain each step and justify your process. Jeff solved a similar
Galina-37 [17]
You have to distribute the 7 to x and 2 so :
7x+14=2x-1
Add one to both sides (inverse operations)
7x+14=2x-1
+1 +1
7x+15=2x
Cross Cancel by subtracting 7x from both sides
7x+15=2x
-7x -7x
15=-5x
Divide by -5
15/-5= -5/-5
X= -3

Svetllana [295]

Answer:

<h2>\ \boxed{(x - 3)(x - 10)}</h2>

Step-by-step explanation:

{x}^{2}  - 13x  + 30

Write -13x as a difference

{x}^{2}  - 3x - 10x + 30

Factor out x from the expression

x(x - 3) - 10x + 30

Factor out -10 from the expression

x(x - 3) - 10(x - 3)

Factor out x-3 from the expression

(x - 3)(x - 10)

Hope I helped!
