Answer:
-3g
Step-by-step explanation:
Let's see: 3+3+3=9
So
3*3=9
and so does
1*9=9
The answer is -2. Since you want to leave your x alone with the number you have to move the 6 to the other side. Now it has become a -6 rather than a 6. It is now -3x=6. (It is 6 because since you removed 6 from the 12). You now wish to leave the x alone so you have to divide by -3. (-3x/-3=6/-3). It should equal to -2. Remember that it is a negative number you are dividing by so you should make the answer negative since they are different signs!
Answer:
x=9
Step-by-step explanation:
The purple expressions are equal because they are Z angles.
So solve
2x + 15 = 5x - 12
=>
15 + 12 = 5x - 2x
27 = 3x
x = 27/3 = 9
