What is the answer to 6(1+8n)=-39+3n

MissTica

For this case we must simplify the following expression:

$6 (1 + 8n) = - 39 + 3n$

We apply distributive property on the left side of the equation:

$6 * 1 + 6 * 8n = -39 + 3n\\6 + 48n = -39 + 3n$

We subtract 3n from both sides of the equation:

$6 + 48n-3n = -39\\6 + 45n = -39$

We subtract 6 from both sides of the equation:

$45n = -39-6\\45n = -45$

We divide between 45 on both sides of the equation:

$n = \frac {-45} {45}\\n = -1$

Answer:

$n = -1$
