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."
Know MoreRestate 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.
To solve equations with variables on both sides, move the constants to the right side of the equation, simplify, move the variables to the left side and simplify. If the variable is negative, multiply both sides by -1 to make it positive.
Full Answer >To solve the quadratic equation ax^2 + bx + c - 0, plug the corresponding numbers into the quadratic formula. Take the opposite of b, and provide the option of adding or subtracting the square root of (b^2 - 4ac). Divide the result by 2a.
Full Answer >Equations containing fractions are solved by first eliminating the denominator of any fractions. In practice, they are solved by converting the fractions into whole numbers.
Full Answer >To solve multi-step equations in algebra, you need to collect like terms, simplify the expressions and follow the order of operations to isolate the variable. Following the order of operations is vital, because other methods generally give incorrect results.
