Systems of equations are collection of multiple equations

We can get system B from system A by: subtracting both equations in system A and by bringing the first equation of system A

The systems of equations are given as:

System A

5x + y = 3

4x - 7y = 8

System B

5x + y = 3

x + 8y= -5

Subtract 4x - 7y = 8 from 5x + y = 3

So, we have:

[tex]\mathbf{5x - 4x + y+7y = 3 - 8}[/tex]

[tex]\mathbf{x + 8y =- 5}[/tex]

This means that, we can get system B from system A by:

  • Subtracting both equations in system A
  • And by rewriting the first equation of system A
