solving for the variables x,y, andz. One more question needs to be considered, what if there is no lone variable? If there is no lone variable substitution can still work to solve, we will just have to select one variable to solve for and use fractions as we solve. Example 7. 5x − 6y= − 14 − 2x +4y= 12 Nolonevariable,

Solving Systems by Substitution Solve the system by substitution. Example 1A: Solving a System of Linear Equations by Substitution y = 3x y = x – 2 Step 1 y = 3x y = x – 2 Both equations are solved for y. Step 2 y = x – 2 3x = x – 2 Substitute 3x for y in the second equation. Solve for x. Subtract x from both sides and then divide by 2.

It is worth pointing out that integration by substitution is something of an art - and your skill at doing it will improve with practice. Furthermore, a substitution which at first sight might seem sensible, can lead nowhere. For example, if you were try to find R √ 1+x2dx by letting u = 1+x2 you would find yourself up a blind alley.
