First of all you need to push the restrictions for x so x not can being never equal 4 and -7 because than these denominators will be equal zero and these fractions undefined
1/(x-4) = 2/(x+7) cross multiple and will get
x+7 = 2(x-4)
x+7=2x-8
x = 15
hope this helped

Answer:
The answer is 25
Step-by-step explanation:
The original price of the meal deal if they would have exactly enough money to buy two of the meal deal is $4
<h3>How to write and solve equation?</h3>
let
x = cost of the meal
Both = 2x - 3
- Jessica = 3/4x
- Callista = 1/2x
3/4x + 1/2x = 2x - 3
(3+2)x / 4 = 2x - 3
5/4x = 2x - 3
5/4x - 2x = - 3
(5-8)x/ 4 = -3
-3/4x = -3
x = -3 ÷ -3/4
= -3 × -4/3
= 12/3
x = $4
