solve using addition and multiplication principles
Did I do this correct? Its been about 10 years since i been to school and am having some issues remembering how to do a lot of this stuff.
-6r-6 is less than or = to -2(2r-4)
my work below:
step 1: -6r-6 < or = to -4r+8
step 2: -6+4r < or = to 8+6
step 3: -2r < or = to 14/2
step 4: -2r div -2r < or = to 7
Answer: r > or = -7
Let me know if i did this correct sorry i dont know how to type the correct characters for less than or = to or divide etc.
Thanks in advance
