u-Substitution. Recall the substitution rule from MATH 141 (see page 241 in the textbook). Theorem If u = g(x) is a differentiable function whose range is an interval I and f is continuous on I, then. ˆ f(g(x))g′(x) dx = ˆ f(u) du. you see why?) Let’s look at . Example 1 Find ˆ sec2(5x + 1) 5 · dx. ˆ sec2(5x + 1) u = 5x + 1. du = 5 dx.

The substitution worksheets include systems where equations are written in standard form and slope-intercept form. Your students will also encounter systems of equations featuring the distributive property, variables on both sides of the equation, and like terms.
Create a pair of linear equations from the given statement, and determine the solution using the substitution method. “Find the numbers if one number is three times of the other number. Also, given that the difference between two numbers is 26”.
In this method, we multiply or divide either one or both equations by a number to make the coefficient of either x-variable or y-variable the same in both equations. Then, we add or subtract the equations to eliminate the variable whose coefficient is the same.
Substitution Method: _________________ one of the equations for one of its variables. . _________________ this expression into the other equation and solve for the other variable. . _________________ this value into the revised first equation and solve for the other variable. .
