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

I would just divide 400 and 10 and then try to come up with the salary
Answer:
PS = 84.5 , x = 43.75
Step-by-step explanation:
Since RQ is congruent to PS, PS is 2x - 3
SR: 4x + 1
Extra at the bottom: 4
4x + 1 + 4 = 180
4x + 5 = 180
- 5 - 5
4x = 175
/4 /4
x = 43.75
Plug in for PS
2 (43.75) - 3
87.5 - 3
84.5
I hope this helps!
