Your answer is 6
Explanation so
L=15
W=4
D=2
15x4=60
60x2=120
Then you use 120divide it by 20 (per hour) and your answer is 6hours
Combine like terms:
subtract x from both sides to get
2x+5=14
subtract 5
2x=9
isolate x:
divide 2 from both sides to isolate x
x=9/2
that's your final answer. unless your teacher wants you to put it in decimal form in which all you do is divide 9÷2.
