Answer:

x should equal -2

Step-by-step explanation:

-4 (3x + 1) + x - 3 = 15

-12x - 4 + x - 3 = 15

-12x + x - 4 - 3 = 15

-11x - 7 = 15

-11x - 7 + 7 = 15 + 7

-11x = 22

-11 ÷ -11x = 22 ÷ -11

x = -2

-11x=22

x=22/-11

x=-2

The original sales price of a jacket to the original price is 3:4. The original price is $64 what is the sales price
natka813 [3]
So we need to find a number that has the same ratio to 64 as 3 has to four. We do this by diving 64 into 4:(this is 16): so the two ratios are different by 16. To find the remaining number we multiply  3 by 16: this is 48. So 48 has the same ratio to 64 as 3 has to 4.

And 48 is the answer!
