The substitution method functions by substituting the one y -value with the other. We're going to explain this by using an example. { y = 2 x + 4 3 x + y = 9 We can substitute y in the second equation with the first equation since y = y. 3 x + y = 9 3 x + ( 2 x + 4) = 9

"Nettet1 Solving By Substitution 2 Linear systems can be solved algebraically. One way is to use substitution. This is easiest when one or both equations is given in terms of either x or y. This means that the x or y is alone on one side of the equal sign. 3 Examples Both equations given in terms of y y 3x 2 y -4x - 7 One in terms of y, one in terms of x " - Linear system substitution
