Which of the following is a solution of the equation 4p 3 13?

Solution. As L.H.S ≠ R.H.S., Therefore, p = 1 is not a solution of the given equation, 4p − 3 = 13.

How do you answer linear equations?

The general steps for solving linear equations are:

  1. Expand all brackets.
  2. Rearrange the terms so that all terms containing the variable are on one side of the equation and all constant terms are on the other side.
  3. Group like terms together and simplify.
  4. Factorise if necessary.
  5. Find the solution and write down the answer.

How do you determine if a number is a solution?

We can determine whether or not a given number is a solution of a given equation by substituting the number in place of the variable and determining the truth or falsity of the result. Example 1 Determine if the value 3 is a solution of the equation 4x – 2 = 3x + 1

How do you know if an equation is true or false?

SOLVING EQUATIONS. Equations may be true or false, just as word sentences may be true or false. The equation: 3 + x = 7. will be false if any number except 4 is substituted for the variable. The value of the variable for which the equation is true (4 in this example) is called the solution of the equation.
