You can put this solution on YOUR website!
x = weekly allowance.
she spends half to play mini-golf.
her parents let her wash the car for 4 dollars.
she ended up with 12 dollars.

x - 1/2 * x + 4 = 12

simplify to get 1/2 * x + 4 = 12.

subtract 4 from both sides of the equation to get 1/2 * x = 8.

solve for x to get x = 16.

her weekly allowance was 16.

she spent half on mini-golf and was left with 8.

her parents gave her 4 to wash the car.

she was left with 12 after all that.
