Answer:
Let Jody's Age be X
Then Jody's Brother age is: 2x - 3
Total is: (2x - 3) + x = 30
Now we solve for x
2x - 3+ x = 30
3x - 3 = 30
3x = 30 + 3
3x = 33
x = 33/3
x = 11
Therefore the age of Jody's Brother is (2×11) - 3 = 19

Answer:
The cost at both Laser Flash and Laser storm would be the same after 4 games
Step-by-step explanation:
Let the number of games be represented as x
Laser flash charges an initial fee of $16 for gear and $4 per game
For Laser flash , the Equation is:
$16 + $4 × x
y= 16 + 4x
Laser storm charges an initial fee of $20 for gear and $3 per game
$20 + $3 × x
y = 20 + 3x
Hence: Equating both costs to each other
Laser flash = Laser Storm
16 + 4x = 20 + 3x
Collect like terms
4x - 3x = 20 - 16
x = 4 games
The cost at both Laser Flash and Laser storm would be the same after 4 games
