A two-step equation is an algebraic problem that takes two steps to solve for a missing number, which is often indicated as "n" (for number), "x" or "y."
Restate the equation with the variable isolated on one side. If 2x + 4 = 8, move 4 to the other side by subtracting 4 from each side of the equation. The new equation is 2x = 8 - 4, or 2x = 4.
The coefficient is the number multiplied by the variable. In this case, divide each side by 2. Thus, 2 / 2 = 1 and 4 / 2 = 2. The result is 1 (x) = 2
Remove the 1, and the answer is x = 2.
A two-step problem is an algebra problem in which you have to solve for at least one other unknown before you can calculate the actual answer to the problem. Some word problems deal with fractions or percentages of an unknown whole.
Full Answer >According to the University of Regina, another way to express solving for y in terms of x is solving an equation for y. The solution is not a numerical value; instead, it is an expression equal to y involving the variable x. An example problem given by the University of Regina is 8 + 5x = 9 - 4y.
Full Answer >In order to solve a linear equation, the variable must be isolated. While there are many ways for this to be accomplished, one thing remains the same in order to correctly solve it - maintain the balance. To maintain the balance of the equation, what is done to one side must be done to the other.
Full Answer >To do two-step equations with integers, simplify the whole numbers in the equation. Isolate x in the equation by adding or subtracting the opposite whole number to both sides of the equation. Divide both sides by the number next to x in the equation to solve for x.
