The equation shows the quadratic formula used correctly to solve the given quadratic equation.

Step-by-step explanation:

The given equation is

           .... (1)

If a quadratic equation is defined as

          ..... (2)

then the quadratic formula is

From equation (1) and (2), we get

Using quadratic formula we get

Therefore the equation shows the quadratic formula used correctly to solve the given quadratic equation.

were is the equation

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
