rememember you can do anything to an equation as long as you do it to boht sides except diviede by zero and when you mulitply by a negative with inequalities (<, <,>,>) remember to flip the sign
sum means add
twice a number means a number times 2 (represented by x)
greater than means >
3 times means multiply
minus is minus
so
sum of twice a number and 5 (2x+5) is greater than (>) 3 times the number (3x) minus 3 (-3)
we now have
2x+5>3x-3
subtract 2x from both sides
5>x-3
add 3 to both sides
8>x
x<8
therefor x is any number less than 8
x can be 7,6,5,4,3,2,1,0,-123189030, π
basically x<8
