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:
- Expand all brackets.
- 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.
- Group like terms together and simplify.
- Factorise if necessary.
- Find the solution and write down the answer.
What are the 3 rules of indices?
Laws of indices
- The first law: multiplication. If the two terms have the same base (in this case.
- The second law: division. If the two terms have the same base (in this case.
- The third law: brackets.
- Negative powers.
- Power of zero.
- Fractional powers.
How do you find the value of I^2?
By definition, i^ {2} is -1. By definition, i 2 is − 1. Do the multiplications. Do the multiplications. Combine the real and imaginary parts. Combine the real and imaginary parts. Do the additions. Do the additions. Multiply complex numbers 3-i and 1+2i like you multiply binomials.
How do you make the denominator of 3-i-1+1I real?
Multiply the numerator and denominator of 3−i 1+1i 3 – i 1 + 1 i by the conjugate of 1+ 1i 1 + 1 i to make the denominator real. Multiply. Tap for more steps… Combine.
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.
