Elga's age = x
Alvin's age = x + 7
x + x + 7 = 97.
Simplify the left side of the equation
2x + 7 = 97.
Subtract 7 from each side
2x = 90.
Divide each side by 2
x = 45
Since x is equal to Elga's age, Elga is 45 years old
The value of TV is 11.
<h3>What is equation?</h3>
An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given:
TU= 8, UV = 3x and TV = x+10
TV= TU + UV
x +10= 8+ 3x
-2x = -2
x= 1
Hence, TV = 1+10= 11.

Step-by-step explanation:
The people will there need to be in order for the second company to be less expensive in 1st restaurant.
Always assume the unknowns are variables when attempting to find them, and then construct the equation using the parameters specified in the question.
Admission fee for 1st restaurant = $1
Charge for 1st restaurant per person = $7
Admission fee for 2nd restaurant = $15
The number of employees required for 2nd restaurant need to have in order to be less expensive = x
Total amount needed for 1st restaurant = $1 + $7 = $8
To make the 2nd restaurant less expensive =
As the total amount of 1st restaurant is $8 and the admission fee 2nd restaurant itself is $15 2nd restaurant is more expensive than the 1st one.
