(x-5)(x+3)
By definition: 4x-10 = 5-x 4x+x = 5+10 5x = 15 x = 3 and y = 2
In order to solve for X, or find out what X equals, you need to get the X alone on one side of the equation. In this case, first you subtract the Y so that the equation becomes 5x=10-y. Then you divide both sides by 5. Now the equation is X=(10-y)/5 (or X equals the quantity of 10-y over 5).
To solve the equation "10 times blank equals 5," you can represent "blank" as a variable, let's say ( x ). The equation becomes ( 10x = 5 ). To find ( x ), divide both sides by 10, resulting in ( x = \frac{5}{10} ), which simplifies to ( x = 0.5 ). Thus, "blank" equals 0.5.
