What question would you ask yourself if you want to solve the equation   4t  =  28mentally?

Short Answer

Expert verified

The question is equivalent to ‘What is the value of the variable‘t’ when28 is divided by’  4.

Step by step solution

01

What is a variable?

A symbol we usually pick letters to be symbols, usually represents a number. Any letter you choose can be a variable.

02

How do you describe an Algebraic Expression? 

A variable is a symbol that stands in for an unknown value in a mathematical expression. A variable expression is a combination of terms and mathematical operations that contains at least one variable. Example a + 2x + 10

03

Apply the concept of equation: 

An equation is a mathematical statement that two expressions are equal. The solution of an equation is the value that when substituted for the variable makes the equation a true statement.

Example: 3x + 5 = 14 is an equation, in which 3x+5 and 14 are two expressions separated by an ‘’equal’’ sign.

04

Step 4: What question would you ask yourself if you want to solve the equation:  – 4 t = 28  mentally?

The equation given in the question:4t=28

On simplification

  4  ·  t  =  28    4  ·  t  4  =  28  4     Divide  both  sides  by  the  coefficient  (    4  )  of  t  t  =    7

From the equation 4t=28 we get the value of the variable‘t’ is negative 7.
