You can solve by subtracting the sets of coefficients and their variables, and then dividing:

8x - 12 = 4x
-8x -8x
—— ——
-12 = -4x
—- ——
-4 -4

3 = x

Hope this helps! :)

At a grocery store, an uncooked beef roast is on sale for $4.99/lb. At the same store, prepared roast beef is at the deli for $2

Mrrafil [7]

For us to find out how many times more expensive is the deli roast compared to the uncooked roast we need to change the units;
cost of 100g=0.221lb is $2.99
cost of 1 lb will therefore be:
1/0.221*2.99
=$13.53/lb
therefore the number of times more expensive the deli roast is compared to uncooked roast is:
[price of 1lb roasted meat]/[price of 1 lb uncooked meat]
=13.53/4.99
=2.7 times
