Question

Two step equation is an equation

• A. that has 2 variables
• B. that involves two sets of equations
• C. in which the solution of the equation is 2
• D. that can be solved using two mathematical operations

Answer 1

The correct option is D that can be solved using two mathematical operations

A two-step equation is an algebraic (it has a variable) equation that can be solved using two mathematical operations.

Example: $2x-3=5$

This equation can be solved using two mathematical operations addition and division

Step 1: Add 3 to both sides of the equation to eliminate the constant on the left side of the equation.
$2x-3+3=5+32x=8$

Step 2: Now, divide both sides by 2 to eliminate 2 on the left side of the equation.
$\frac{2x}{2}=\frac{8}{2}x=4$
