Solve for a _(a-150)= 1500

To solve the equation, you need to isolate the variable 'a'.

Start by distributing the coefficient '-1' to the terms inside the parentheses:

-1(a - 150) = 1500
-a + 150 = 1500

Next, subtract 150 from both sides of the equation:
(-a + 150) - 150 = 1500 - 150
-a = 1350

Finally, multiply both sides by -1 to solve for 'a':
-a * -1 = 1350 * -1
a = -1350

The solution to the equation is a = -1350.
