Answer:
The professor wanted to order his class of 43 new handbooks. Each handbook was $7. What will be the total amount he will be spending on handbooks?
<span>13n-6p-11n=2p for n
Anser: n=4p</span>
Set it up like this, going from words on the page to letters and variables:
-3(2x+5) = -57. Twice a number is 2x, increased by 5 is 2x+5, and that is multiplied by -3 to get a total of -57. Distribute the -3 into the parenthesis to get -6x - 15 = -57. Move the 15 over by addition to get -6x = -42. Divide both sides by -6 to get that x = 7
Answer:
-1x-3
Step-by-step explanation:
-6x+5x=-1x
-10+7=-3
