Solve for x?
0 = -9/5 x -9
0 = -9/5 x -9
9 = -9/5x
9/-9/5 = x
9* (-5/9) = x
-45/9 = -5 = x

solve the following simultaneous equations by using cramer’s rule 3x-2y=3 ; 2x+y=6
To solve for x in the equation 0 = -9/5 x - 9, we need to isolate the variable x.
Step 1: Start by subtracting 9 from both sides of the equation:
0 + 9 = -9/5 x - 9 + 9
Simplifying the equation further, we have:
9 = -9/5 x
Step 2: Next, to isolate x, multiply both sides of the equation by -5/9:
(9) (-5/9) = (-9/5 x) (-5/9)
Simplifying this equation, we get:
-45/9 = x
Step 3: Finally, reduce the fraction -45/9 to its simplest form:
-5 = x
Therefore, the solution to the equation 0 = -9/5 x - 9 is x = -5.
