Answer:

Step-by-step explanation:

$3[-x + (2 x + 1)] = x -1\\\\\mathrm{Expand\:}3\left(-x+\left(2x+1\right)\right):\quad 3x+3\\3x+3=x-1\\$

Collect like terms

$3x -x =-1-3$

Add similar elements

$2x = -4\\\\\mathrm{Divide\:both\:sides\:by\:}2\\\frac{2x}{2}=\frac{-4}{2}\\\\Simplify\\\\x = -2$

15d^3+30d^2+30d/3d3 what is the answer if you divide the following

lawyer [7]

When you separate them
$\frac{15d^{3} }{ {3d}^{3} } + \frac{30d^{2} }{ {3d}^{3} } + \frac{30d }{ {3d}^{3} } = x$
Solve them separately:
$5 + \frac{10}{d} + \frac{10}{ {d}^{2} } = x$
Remove the denominators:
$5 + 10 {d}^{ - 1} + 10 {d}^{ - 2} = x$
Find GCF (Greatest Common Factor):
$5(1 + 2 {d}^{ - 1} + 2 {d}^{ - 2} ) = x$
