Multiply $530.40 by 3/4. You get the equation

If you simplify this, you get the solution of $397.80
$397.80
If you would like to solve y = x - 4 and 2 * x + y = 5, you can do this using the following steps:
y = x - 4
2 * x + y = 5
_____________
2 * x + (x - 4) = 5
2 * x + x = 5 + 4
3 * x = 9 /3
x = 9 / 3
x = 3
y = x - 4 = 3 - 4 = -1
The correct result would be x = 3 and y = -1.
I agree that and means multiplication, but in this problem it says OR. When you have or, you have to add. 1/2 +1/6 would be 2/3
