8(2r-3)-r=3(3r+2)
16r-24-r=9r+6
16r-r-9r=6+24
6r=30
R=30÷6
R=5

Answer:
15km
Step-by-step explanation:
If 1cm is 5km and the towns are 3 cm apart you times the the real life distance (5km) by the distance in cm (3cm)
Given solution: should be solution.
8p (>/=) -7 8p (>/=) -78p (>/=)-7 8p (>/=) -7 SAME
8p/8 (=) -7/8 8p/8 (>/=) -7/8 DIFFERENT
p (=) -7/8 p (>/=) -7/8 DIFFERENT
The error in the given solution was that the inequality sign > was taken out of the equation. It should not be because the expression is an inequality. p can be any number that is greater than or equal to -7/8. It is not limited to only -7/8.
