Answer: x = -3/2
Step-by-step explanation:
I am assuming that you want to solve for x.
To solve for x, we need to isolated x on one side
-2x = 4x + 9
Subtract 4x from both sides
-2x - 4x = 4x + 9 -4x
Simplify
-6x = 9
x = -9/6
x = -3/2
As always, don't forget to check your work:
-2x = 4x + 9
-2(-3/2) = 4(-3/2) + 9
-3 = -12 + 9
-3 = -3, so our answer is correct.
Hope this helps.
Cheers,
Andy
