2 consecutive odd integers....x and x + 2
x + 44 = 3(x + 2)
x + 44 = 3x + 6
44 - 6 = 3x - x
38 = 2x
38/2 = x
19 = x
x + 2 = 19 + 2 = 21
ur 2 numbers are : 19 and 21

Answer:
$90.00
Step-by-step explanation:
<em>Larrie and Lester went shopping. They both went with equal amount of money.</em>
Let initial amount = x
Larrie = Lester = x
<em>Larrie spent $120.00 and Lester spent $150.00.</em>
Amount left (Larrie) = x - $120.00
Amount left (Lester) = x - $150.00
<em>At the end of the shopping Lester had 2/3 of what Larrie had left.</em>
Amount left (Lester) = 2 / 3 (Amount left (Larrie)
x - 150 = 2/3 (x - 120)
solving for x;
3 (x - 150) = 2 (x - 120)
3x - 450 = 2x - 240
3x - 2x = -240 + 450
x = 210
<em>How much money did Latrine have after shopping?</em>
Amount left (Larrie) = x - $120.00
Amount left (Larrie) = $210.00 - $120.00
Amount left (Larrie) = $90.00
