How do you solve

2 (x - 5) = - 11

https://socratic.org/questions/how-do-you-solve-2-x-5-11

(x = - \frac{1}{2}

2 (x - 5) = - 11

2 \cdot (x) + 2 \cdot (- 5) = - 11

2 x - 10 = - 11

2 x - 5 = x - 1

2x-5=x-1 One solution was found : x = 4 Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : ...

How do you solve

2 x - 5 < x + 1

https://socratic.org/questions/how-do-you-solve-2x-5-x-1

Gió May 11, 2015 You can solve it as a normal equation isolating

x

on one side (changing signs when necessary) and "reading", at the end, the result:

2 x - x < 5 + 1

How do you solve

- 2 (x - 5) = - 4

https://socratic.org/questions/how-do-you-solve-2-x-5-4

- 2 x + 10 = - 4
