Add 8 to both sides (-5)
-8 is going to cancel out so it will get ride of -8 and it will only add -5
-5+8=3
then all you have left is x
so it would be x=3
Simply the equation by using cross-multiplication, you get 30=5q
Then you swap sides of the equation, you get 5q=30
Then you divide both sides of the equation by 5
Your answer is q=6
Since she buys 12 steaks that are each 3/4 of a pound, you multiply 12 by 3/4.
12* 3/4=9
Silvia buys a total of 9 lbs of steak. To find the amount that Silvia spends for each kind of steak, divide $90 by 9.
If it asks for that amount, the answer is $10.
2x+5=27
subtract 5 from both sides:
2x=22
divide by 2 on both sides:
x=11
