# How do you solve 8( 12- 2x ) = 5x + 12?
Jun 17, 2018
$x = 4$
#### Explanation:
Multiply out the brackets
$8 \times 12 = 96$
$8 \times \left(- 2 x\right) = - 16 x$
to give
$96 - 16 x$
on the left side of the equation. Therefore
$96 - 16 x = 5 x + 12$
Then rearrange the whole equation to get all the $x$'s on... |

# How do you calculate tension in a pulley?
Calculate the tension in the rope using the following equation: T = M x A. Four example, if you are trying to find T in a basic pulley system with an attached mass of 9g accelerating upwards at 2m/s² then T = 9g x 2m/s² = 18gm/s² or 18N (newtons).
