Which numbered choice represents the solution to the system y=2x+4 -6x+3y=12

Question

 

Which numbered choice represents the solution to this system?
	1) (2,8) 2) (-3,-2) 3) (0,4) 4) All are solutions.

 

 

Answer 1

y=2x+4 ...or y-2x=4

-6x+3y =12...divide bi 3 &  yu get y-2x=4

the 2 inputs R the same

yu need 2 INDEPENDENT equashuns tu solve for 2 dont-noes

Answer 2

Answer 4, all are solutions because there is in fact only one equation: y=2x+4.

The other can be written: -2x+y=4 by dividing through by 3, and this equation is y=2x+4.

The ordered pairs all fit the equation, which is simply defining a linear relationship between x and y.
