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
67n - 58 = n - 36
hope this helps, have a great day!

Answer:
Step-by-step explanation:
Remark
You need the work done (I think), and the power developed from the givens. This question is just a straight forward application of the formulas for work and power.
Givens
F = 100 N
d = 5 meters
t = 15 seconds
Formulas
W = F * d
Power = F * d / t
Solution
<u><em>Work</em></u>
W = 100 N * 5 meters
W = 500 Newton Meters or 500 J
Work = 500 Joules
<u><em>Power</em></u>
P = F * d / t
Power = 100 * 5 / 15
Power = 33.3 Watts.
