Is p -1 a solution to the equation 6(p and ndash 4) -30p?
It depends what 6(p - 4) - 30p is supposed to equal. Substituting p = -1, gives: 6((-1) - 4) - 30(-1) = 6×-5 - 30×-1 = -30 + 30 = 0 Only if 6(p - 4) - 30p = 0 is p = -1 a solution. Otherwise it is not a solution.
Is x equals 1 a solution of the equation 2 - 8x?
No. That is because 2 - 8x is an algebraic expression, not an equation. And since it is not an equation, it does not have a solution.
Does an equation has a solution?
Yes and sometimes it can have more than one solution.
What is a solution to the equation 5x 2y-1?
Without an equality sign it cannot be classed as an equation therefore it follows that there is no solution.
Isha sharma writes three liner equations in two variables as under 3x plus 2y equals 5 5x-7y equals -2 6x plus 4y equals 10which pairs has no solution?
There is no such pair. The solution to equation 1 and equation 2 is x = 1, y = 1. The solution to equation 2 and equation 3 is x = 1, y = 1. And the solution to equation 1 and equation 3 is any point on the line 3x + 2y = 5 - an infinite number of solutions. The fact that the determinant for equations 1 and 3 is zero (or that they are not independent) does not mean that there is no solution. It means that there is no UNIQUE solution. In this particular case, the two equations are equivalent and so have an infinite number of solutions.

What is an equation that has no solution called?
An equation that has no solution is called an equation that has no solution.
An example of an equation and its solution?

Is x equals 1 a solution of the equation 2 - 8x?
No. That is because 2 - 8x is an algebraic expression, not an equation. And since it is not an equation, it does not have a solution.
What fraction 1 is 30p?
It is 1/30.
How many 30p are in 1 pound?
There are 3 30p's in £1. But you still have 10p left over needed to make the pound.
Does an equation has a solution?

0
What is the solution of the equation 5x 1 45?
Without any equality and not knowing the plus or minus values of 1 and 45 it is not an equation so therefore it has no solution.
What is r times 1 equals 1?
It is a linear equation in one variable r. The solution to the equation is r = 1.
