Hope this helps!
12x >9(2x-3)-15
distribute
12x> 18x-27-15
combine like terms
12x>18x -42
subtract 18x from each side
12x -18x >18x-18x-42
-6x>-42
divide by -6 which will flip the inequality
-6x/-6<-42/-6
x<7

Answer:

Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -x + 5
// Plug this in for variable y in equation [1]
[1] x - 2•(-x +5) = 8
[1] 3x = 18
// Solve equation [1] for the variable x
[1] 3x = 18
[1] x = 6
// By now we know this much :
x = 6
y = -x+5
// Use the x value to solve for y
y = -(6)+5 = -1
Solution :
