What are the 2 steps to solve a two step equation?
The general two steps to solve two step equations are:
- Step 1: Add or subtract to isolate the variable.
- Step 2: Multiply or divide to determine the value of the variable.
What order do you solve 2 step equations?
1) First, add or subtract both sides of the linear equation by the same number. 2) Secondly, multiply or divide both sides of the linear equation by the same number. 3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.
What are the 2 golden rules of solving an equation?
Do unto one side of the equation, what you do to the other! If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.
How old am I if 400 reduced by 2 times my age is 244?
78 years old
400 is reduced by twice the person’s age to get 244. Therefore, the age of the person is 78 years. Hence, he is 78 years old if 400 reduced by twice his age is 244.
What is an example of a two-step word problem?
A two-step problem is a word problem that requires two operations to solve it, for example: I buy a magazine costing 83p and a pencil costing 45p. I pay with a voucher that gives me 20p off the things I am buying.
What is the 2 step rule in math?
A two-step equation is an algebraic equation that takes you two steps to solve. You’ve solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.
How can you determine a good first step in solving a two-step equation?
To solve two-step equations, the first step is to simplify the variable equation by using addition or subtraction. If a number is added or subtracted with the variable, do the opposite or inverse operation on both sides of the equal sign.
