Hb=3.5, hd=2.25, hb+hd=7,
From the third, we can say hb=7-hd and we are told that:
3.5hb+2.25hd=19.5 using hb found above in this equation gives you:
3.5(7-hd)+2.25hd=19.5
24.5-3.5hd+2.25hd=19.5
-1.25hd=-5
hd=4

Step-by-step explanation:
You can solve this quickly by finding the difference in prices first.
7.49 - 6.99 = .50 difference
Now - multiply 4 shirts by .50 = $2
That is the SAVINGS for 4 shirts at the cheaper place
It would be 3:5 because 47 round up to 3:50
Answer:

Step-by-step explanation:
We are asked to solve the given equation:
.
To solve this equation we will combine like terms by moving all the terms containing x to the left hand side of equation and terms without x to right hand side of equation.
Let us add 8x to both sides of our equation.



Let us subtract 8 from both sides of our equation.


Upon dividing both sides of our equation by 6 we will get,



Therefore, the value of x equals 1 will satisfy our given equation.
