- The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation. In this way, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved.

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.
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.

Mar 23, 2024 · Solve a System of Equations by Substitution. We will use the same system we used first for graphing. {2x + y = 7 x − 2y = 6. We will first solve one of the equations for either x or y. We can choose either equation and solve for either variable—but we’ll try to make a choice that will keep the work easy.
