Step-by-step explanation:
It takes Lucas 3 hours to cycle from his home to his friend’s village:
3 hours • (a certain speed) = distance in miles
If he travels 5mph slower, it will take him 1.5 hours longer:
4.5 hours • (the same speed - 5mph) = the same distance in miles
4.5 • (x - 5) = 3x
4.5x - 22.5 = 3x
1.5x = 22.5
x = 15mph
3hours • 15mph = 45 miles
x = 
isolate 5x by adding c to both sides of the equation
5x = k + c ( divide both sides by 5 )
x = 
Answer:
x=1
Step-by-step explanation:
5x+9 - x= 13
Combine like terms
4x +9 = 13
Subtract 9 from each side
4x+9-9 = 13-9
4x = 4
Divide each side by 4
4x/4 = 4/4
x=1
