∙ 13y ago
273x+1 = 9
33(3x+1) = 32
9x+3 = 2
9x = 2-3
9x = -1
x = -1/9
Check: 27(3*-1/9)+1 = 9

Is c equals ab to the second power a equation or expression?
It is an equation ... Anything with an equals is an equation 2+b=6 Anything without an equals is an expression 2+a
What do you call the solution of a equation derived from an original equation that is not a solution of the original equation?
That's an extraneous solution. You need to check for these when algebraically solving equations, especially when you take both sides of an equation to a power.
What is 3x to the 2nd power equals -7?
An equation.

Is y equals 5x2 plus 2 a linear equation?
Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
Solve 5 to the power of x equals -25?

Why is an equation written in the form Ax plus By equals c called a linear equation?
The equation contains variables which are only raised to the first power.
Does an equation have one true solution?
-- If the equation has only one variable (like 'x' or 'y'), and the only power of the variable anywhere in the equation is '1', then the equation has one solution. -- If the variable appears raised to powers higher than '1', then there are as many solutions as the highest power of the variable. -- If the equation has two or more variables, then there are an infinite number of solutions.
