Answer:
r>6
Explanation:
10<3r+3 x -3+1
Solve by distributing:
10<3r-9+1
Simplify the arithmetic:
10<3r-8
Simplify the arithmetic:
3r-8>10
Add 8 to both sides:
3r-8+8>10+8
Simplify the arithmetic:
3r>10+8
Simplify the arithmetic:
3r>18
Divide both sides by 3:
3r/3 > 18/3
Simplify the fraction:
r>18/3
Find the greatest common factor of the numerator and denominator:
r> 6x3/1x3
Factor out and cancel the greatest common factor:
r>6
