SOLVING a System Of Equation
Using Eliminations
Solving a system of equation using eliminations is when an equations have a negative and the other have a positive I have to use
addition to take a variable out and when I finish doing this I have to subtract the other numbers that doesn’t have a variable so I
can leave the number that have a variable with it. A "system" of equations is a set or collection of equations that you deal with all
together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear
system is one with two equations and two variables. Some time the elimination method requires multiplication first than either
addition or subtraction.
Solve:
3x – 5y = 7
STPEP 1: 2x + 5y = 13
2x + 5y = 13
STEP 2: 2(40) + 5y = 13
STEP 3: 8 + 5y + 13
STEP 4: 5y = -8
STEP 5: y = 1
STEp1: 5x + 0 = 20
STEP 2: x = 4
This is an example of solving a system of equation using eliminations by using those step to solve this equation. Those
are the step that you have to use to solve this equations for solving a system of equation.
