Question

When solving an equation, which of the following is true

A. Use properties of equality to get the variable and constant terms on the same side of the equation

B. Always isolate the variable on the left side of the equation

C.Use properties of equality to get the variable on one side of the equation and constant terms on the other.

Answer 1

C. Use properties of equality to get the variable on one side of the equation and constant terms on the other.

Explanation:

In solving an equation, It is true that properties of equality should be used by putting the variable on one side and the constant on the other side.

Now let use an example to drive this;

Given:

2x - 9 = x + 8

This is an equation, and what we have on both sides should be equal.

Collect like terms;

2x - x = 8 + 9

x = 17

So the solution is 17.

This is the best way to solve an equation.
