**Solving Systems Of Equations By Substitution Worksheet 8th Grade** Example 2 In order to use the substitution method we ll need to solve for either x or y in one of the equations Let s solve for y in the second equation Now we can substitute the expression 2 x 9 in for y in the first equation of our system 7 x 10 y 36 7 x 10 2 x 9 36 7 x 20 x 90 36 27 x 90 36 3 x 10 4 3 x

In this unit we learn how to write systems of equations solve those systems and interpret what those solutions mean in a real world context If you re seeing this message it means we re having trouble loading external resources on our website Math 8th grade Unit 4 Systems of equations 700 possible mastery points Mastered Ok let s take the same problem and break it down very carefully 2y x 7 x y 4 so the second equation above denotes that x correlates to y 4 So let us substitute y 4 on the top of the equation replacing the position of the value x Making it 2y y 4 7 Let us find the value of y
