# How do you solve 4x-(3x+11)=-11?

$x = 0$

#### Explanation:

We can expand $- 1 \left(3 x + 11\right) = - 3 x - 11$

$\implies 4 x - 3 x - 11 = - 11$

$\implies 4 x - 3 x - 11 + 11 = - 11 + 11$

$\implies 4 x - 3 x + 0 = 0$

we know $4 x - 3 x = x$

You have to factor the equation and make the left side into $4 x - 3 x - 11$ since you factored the negative sign and $4 x - 3 x - 11 = x - 11$ because you have to add like terms. Then we add 11 to each side so the whole equation will be $x - 11 = - 11$. The final equation is $x = 0$.
