Question

Karim's dog weighs 1.5 pounds less than double the weight to Frank's dog. Karim's dog weighs 15 pounds. Which equation and solution can be used to find w, the weight of Frank's dog?

Answer 1

1. Because

info given:
Karim's dog = 15 pounds
Frank dog = 2x more pounds than Karim's dog + 1.5 pounds

(Karim) Equation 1: 15 = Frank
(Frank) Equation 2: 2w + 1.5

joining equation 1 and 2

15 = 2w + 1.5

Solve

15 - 1.5 = 2w
13.5 = 2w ÷ 2
w = 6.75
