To solve the given equation, we first need to expand and simplify the left side of the equation.
Expanding the equation:3(x - 1)^2 - 3x(x - 5) = 213(x^2 - 2x + 1) - 3x^2 + 15x = 213x^2 - 6x + 3 - 3x^2 + 15x = 219x - 3 = 21
Now we can solve for x:9x - 3 = 219x = 24x = 24/9x = 8/3
Therefore, the solution to the equation is x = 8/3.
To solve the given equation, we first need to expand and simplify the left side of the equation.
Expanding the equation:
3(x - 1)^2 - 3x(x - 5) = 21
3(x^2 - 2x + 1) - 3x^2 + 15x = 21
3x^2 - 6x + 3 - 3x^2 + 15x = 21
9x - 3 = 21
Now we can solve for x:
9x - 3 = 21
9x = 24
x = 24/9
x = 8/3
Therefore, the solution to the equation is x = 8/3.
