A number is divided by 4, and the quotient is added to 3. The result is 24. What is the number? (Please show how you got it) (n/4) + 3 = 24

84

Step-by-step explanation:

(x/4) + 3 = 24

so in this case try and make x the subject or in other words try to leave x on one side of the equation.

(x/4) = 24 - 3

(x/4) = 21

now multiply 21 by 4 using cross multiplication

so x= 84

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
