Guys: Here is another method for solving system of 2 equations with 2 unknowns, take another example, after exchanging the samples with the method of Equalization. Here is the
METHOD OF REPLACING:
2x + y = 5 To solve this system, using substitution, we do well:
3x - 2y = -3
° Clear one of the variables in the equations
2x + y = 5 y = 5 - 2x (i)

3x - 2y = -3
3x - 2 (5 - 2x) = - 3 Substituting (replace) the expression (i) in the other equation of the system
3x - 10 + 4x = - 3 Solving the new equation and find x.
7x = - 3 + 10
x = 7: 7
x = 1 Value of x
y = 5 - 2.1 We replace in (i) the value of x we \u200b\u200bgot, and we learn and
y = 5 - 2 then y = 3
The solution is the ordered pair (1, 3). We can see
Substituting these values \u200b\u200binto the original equations
2. 1 + 3 = 5
3.1 - 2.3 = -3
Again: Now exchange systems and do it with the methods changed.
Application Exercises: Solve
sig. systems of linear equations with the substitution method. Check the solutions to get and make the graphical representation. Remember that the graphic should be clear and
5x - 3y = 1 2x = y (x - 2): 3 = y
x + y = -1 x - y = 2 x + y = 2
