Your answer would be x=-10.5
First distribute -2/3 to 3x and -9
-2x+6=15
Then subtract 6 from both sides
-2x=9
Divide both sides by -2
x=-4.5
Answer:
D
Step-by-step explanation:
566,000/60 = 9433 1/3 = 9433.3
12x - 4y = -8
y = 3x + 2
Rewrite the first equation
12x + 8 = 4y
3x + 2 = y
As you see, the first and second equation are actually the same, meaning there's an infinite number of solutions.
6 : 2/3.....multiply by 3
18 : 2...reduce
9:1 or 9/1
