Admin Which operation should be done on both the sides of equation?
Solution. And 9 i.e constant in LHS only should be subtracted on both sides.
Why do you have to do operations to both sides of the equation?
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.
What does it mean if both sides of an equation are the same?
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true.
What is done to one side of the equation must also be done to the other side Why?
Answer: An equation is like a balance scale or a see-saw. To keep it balanced, whatever we do to one side of the equation, we must also do to the other side to keep the equation balanced. (Otherwise, the equation makes no mathematical sense and is useless to us.)
When we perform the same operation on both sides of the equation the equation stays in blank?
Addition Property of Equality If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.
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.
What is the second step to solving a two step equation?
Solving two-step Equations Step 2 The second step is to isolate the variable by multiplication or division. In the problem, x is being multiplied by two. The inverse of multiplication is division, so you should divide both sides of the equation by 2.
