To solve an algebraic expression, simplify the expression by combining like terms, isolate the variable on one side of the equation by using inverse operations. Then, solve the equation by finding the value of the variable that makes the equation true.
20 maj 2024 · We can calculate the residual as: e = y − ŷ. where: e – Residual; y – Observed value; and; ŷ – Predicted value. For instance, say we have a linear model of y = 2 × x + 2. One of the actual data points we have is (2, 7), which means that when x equals 2, the observed value is 7.
