isolate the variable

It is to make the variable the subject of the equation.

A constant.

If both sides of an equation are not equal, it won't be an equation any more! In solving equations, the strategy is to change both sides in the same way, so that an 'equivalent' equation is produced. An equivalent equation has the same solution as the original equation. You are aiming for an equation in which the variable is alone on one side. The quantity on the other side is the solution.

Unfortunately, this website cannot reproduce some crucial mathematical signs. If the equation is 4y = 3, divide each side by 4. y = 3/4 If the equation is 4y + 3 = 0, subtract three from each side, then divide each side by 4. 4y = -3 y = -3/4

A) Divide both sides of the equation by 4.

As it appears, there is no equation but an algebraic term.

When you solve a one-variable equation, your goal is to isolate the variable.To isolate the variable means to make it be alone on one side of the equals sign.In the equation shown here, you can isolate the variable by subtracting 9 from both sides of the equation and simplifying

Divide both sides of the equation by 15

It is called a constant.

Multiply both sides of the equation by 1.5

No. In the variable x, alone, it is linear. In the variable y, alone, it is linear. But taken together, in x and y, you have a term which contains xy - that is, a term in which the powers of the unknowns add to 2. So the equation is not linear.
