When you write your answer the variable should be on the left?

Scientists like to say that the “independent” variable goes on the x-axis (the bottom, horizontal one) and the “dependent” variable goes on the y-axis (the left side, vertical one).

Do equations go left to right?

This phrase stands for, and helps one remember the order of, “Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction”. Multiplication and Division (from left to right) Addition and Subtraction (from left to right)

Does the variable have to be on the left?

This is pretty standard. When you’re solving, the variable will end up wherever it ends up. When you’re writing out the solution, the variable goes on the left.

How do you know if an equation is right?

If the numbers you get from evaluating the two expressions are the same, then the given value is a solution of the equation (makes the equation true). If the numbers don’t match, the given value is not a solution of the equation (makes the equation false).

What is the left side of an equation called?

In mathematics, LHS is informal shorthand for the left-hand side of an equation. Similarly, RHS is the right-hand side. The two sides have the same value, expressed differently, since equality is symmetric.

Is algebra right to left?

The order of operations is Parenthesis, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This can be remembered in two ways: “Please Excuse My Dear Aunt Sally” or PEMDAS. The following list, from top to bottom, is the order of operations in Algebra.

When solving equations what is done to one side of the equation must also be done to the other side?

When solving equations with variables on one side of the equation there is one main rule to follow: whatever you do to one side of the equals sign you must do the same to the other side of the equals sign.

How do you determine LHS and RHS?

The expression on the right side of the “=” sign is the right side of the equation and the expression on the left of the “=” is the left side of the equation. x + 5 is the left-hand side (LHS) and y + 8 is the right-hand side (RHS).

How many sides does an equation has write the number?

An equation is written as two expressions, connected by an equals sign (“=”). The expressions on the two sides of the equals sign are called the “left-hand side” and “right-hand side” of the equation.
