An equation with two equal signs is not a valid mathematical expression, as an equation should have only one equal sign to show the balance between the two sides. If you encounter an expression with two equal signs, it may be a mistake or a misunderstanding of the mathematical concept. To solve an equation correctly, ensure there is only one equal sign and follow the standard procedures for isolating the variable on one side of the equation.

SteveAn equation with two equal signs is really to explicit equations (or three implicit ones).
For example, expession 1 = expression 2 = expression 3 is equivalent to
expression 1 = expression 2
AND
expression 2 = expression 3
and, by transitivity,
expression 1 = expression 3
So you need to solve two of the above three.

What is y in y equal 4x-2?
Sorry, but it is impossible to solve this equation by itself. Since you have two unknowns, you need two equation.

An equation that states that two ratios are equal?
An equation that states that two ratios are equal is a proportion.
A mathematical statement that two expressions are equal?
That's an equation.
How do you solve algebra with two variables?
Algebraic equations with two variables will need two equations to be able to solve it. Then, you can solve it with either substitution, adding/subtracting them together, or graphing! Those are the basic steps... For example: An instance of substitution: 2x + 1 = y + 2 x + y = 3 You could isolate y in the second equation to equal y = 3-x. Then in the first equation, substitute y with what it equals to 2x + 1 = 3-x+2 Then you can solve for x!
