solve this equation
0.04x-0.9x=5.16
combine the x terms by adding their coefficients. then undo normally
To solve the equation 0.04x - 0.9x = 5.16, we need to combine the x terms by adding their coefficients:
-0.86x = 5.16
Next, we can undo this by dividing both sides of the equation by -0.86:
x = 5.16 / -0.86
Now, we can simplify this expression:
x = -6
Therefore, the solution to the equation is x = -6.
