What is the difference between numerical expression and equation?
a numerical expression is just an expression without any equal or unequal signs, e.g. (a+2b)c or 5x-6y an equation shows two expressions with an equal sign, e.g. (a+2b)c = 53 or 5x-6y = 3k2-7k+21
What is 4X plus 6Y?
It is a binomial expression in X and Y.
What is the solution set of the given equation 4y - 6y plus 9y equals -2?
4y - 6y + 9y = -2Combine like terms on the left side:7y = -2Divide each side by 7:y = -2/7The solution set is: { -2/7 }
8x-6y equals 18 and 4x-6y equals 6?
8x - 6y = 184x - 6y = 6from the first equation:6y = 8x - 18substitute this value in the second equation:4x - (8x - 18) = 64x - 8x + 18 = 6-4x = 6 - 18-4x = -12x = 3Solve for y :8 x 3 - 6y = 1824 - 6y = 186y = 6y = 1
How do you solve 3x-7?
10
Is 6y-7 an equation or an expression?
It is an expression because it has not got an equality sign
4x-6y -12 what is the answer to this?
There is no equation in the question: only an expression. An expression has no answer.

What is the solution to the equation 11y 5-15 6y?
It is not an equation because there's no equal sign but it is an expression that can be simplified to: 17y-10
How do you do 5x plus 6y plus 4-3x-3 equals?
All that you can do is to simplify the left hand side of the "equation" to the expression 2x + 6y + 1. Since the right hand side of the original "equation" is not given, it is, in fact an expression and cannot be solved. In any case, one linear equation in two variables cannot be solved.
What is the answer to 25x-2y plus 13x-6y plus x?
There can be no answer because the question contains an expression, not an equation or inequality.
What is 6y-4 called in an equation?
6y-4 called in an equation = 2
Is 7x plus 2y equals 16 and -21x-6y equals 24 a no solution?
Multiplying the first equation by -3 gives -21x - 6y = -48 but the other equation gives 24 as the value of the same expression, so you are correct, there is no solution
What does 10x 6y equals?
10x and 6y are terms of an algebraic expression
What is 10-6y-104?
It is an algebraic expression that can be simplified to: -6y-94
How do i factor the expression y2 plus 6y-16?
It is: (y+8)(y-2) and knowing how to use the quadratic equation formula does help.
Is 5 a solution to 4x plus 7?
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
