Answer:
-2.33
Step-by-step explanation:
Let the number be denoted as "x"
-45x + 12 = 117
-45x = 117-12
-45x = 105
x = 105/-45
x= -2.33
Since y=x-4 you would simply just plug that into 'y' on the other equation, given: x-4=3x+2.
Subtract x from both sides, it will leave you with -4=2x+2.
Next you would subtract 2 from both sides, leaving you with -6=2x.
All you need now is to get rid of the coefficient in front of 'x' so you divide both sides with 2, leaving you with your answer: -3=x.
Answer: -3=x
