Answer:
B
Step-by-step explanation:
The first choice is true.
The second is not true.
Third is true.
I think the last is true (not sure)
5 + 4x
I think that’s right
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
