Gary bought 32 lb of potting soil this week this amount is 6 lb more than twice the amount of potting soil he bought last week a

lys-0071 [83]

Let the amount of potting soil bought last week be $x$

We know that this week's amount is 32 lb
We also know that this week's amount is double the amount of last week's plus 6 lb

So we write the equation:
$32 = 2x+6$

Solving this equation:
$32=2x+6$ ⇒ subtracting 6 from both sides
$32-6=2x+6-6$
$26=2x$ ⇒ Dividing both sides by 2
$\frac{26}{2}= \frac{2x}{2}$
$13=x$

The answer is: 13
