Answer:
y=-1x-5
Step-by-step explanation:
Answer:
To get system B, the SECOND equation in system A was replaced by the sum of that equation and the FIRST equation multiplied by FOUR. The solution to system B IS de same as the solution to system A
Step-by-step explanation:
x-y=3 equation 1
-2x+4y=-2 equation 2
so, multiplying by four the equation 1 we have
4x-4y=12 equation 3
later sum equation 3 and equation 2 we have
2x=10
Answer:
Step-by-step explanation:
The solution to a system of linear equations is the ordered pair (or pairs) that satisfies all ... Solve the following system of equations by substitution. ... For example, consider the system of equations below: 3x + 2y = 6 x − y = 8 ... 12x + 18y = 39
