-----------------------

4x + y = 12

5x -3y = 15

Rewrite the equations in slope intercept form. y=mx+b

Solution ( , )

4x + y = 12

5x -3y = 15

Rewrite the equations in slope intercept form. y=mx+b

Solution ( , )

x + y = -1

3x – 2y = 12

Rewrite the equations in slope intercept form. y=mx+b

Solution ( , )

x + y = -1

3x – 2y = 12

Rewrite the equations in slope intercept form. y=mx+b

Solution ( , )
