Given the equation p=2n-3 , what is p when =3

3

Step-by-step explanation:

Hello!

It is asking for the answer is p is equal to 3 so we put 3 in for p

3 = 2n - 3

Add 3 to both sides

6 = 2n

Divide both sides by 2

3 = n

The answer is 3

Hope this helps!

n = 3

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

*3-(2*n-3)=0

Pull out like factors:

*6 - 2n  =   -2 • (n - 3)

Solve:

*-2   =  0 (This has no equation so we solve for the next side.)

*n-3 = 0 (Add 3 to both sides)

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
