Question

13. – 5x – 10 = 2-2(x – 4)

Answer 1

Answer:

$\boxed{ \boxed{ \bold{ \purple{ - 6.67}}}}$

Step-by-step explanation:

$\sf{ - 5x - 10 = 2 - 2(x - 4)}$

Distribute 2 through the parentheses

⇒$\sf{ - 5x - 10 = 2 - 2x + 8}$

Move constant to right hand side and change it's sign

Similarly , Move variable to left hand side and change it's sign

⇒$\sf{ - 5x + 2x = 2 + 8 + 10}$

Collect like terms

⇒$\sf{ - 3x = 2 + 8 + 10}$

Add the numbers

⇒$\sf{ - 3x = 20}$

Divide both sides of the equation by -3

⇒$\sf{ \frac{ - 3x}{ - 3} = \frac{20}{ - 3} }$

Calculate

⇒$\sf{x = - 6.67}$
