1/2 n + 10.5 =3.5 find the value of n

n= -14

Step-by-step explanation:

First, convert into a decimal:

as a decimal is 0.5

now the equation is 0.5n+10.5=3.5

Move the constant to the right and change its sign:

0.5n=3.5-10.5

Calculate the difference:

0.5n=3.5-10.5

0.5n= -7

Divide both sides of the equation by 0.5:

0.5n÷0.5= -7÷0.5

n= -14

there are infinitely many solutions.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
