Question

y = 2x + 4 2x - y = 6 Solve the system of equations using substitution. A) (2,8) B) (2,-8) C) (10,24) D) no solution

Answer 1

Answer 2

So we know that y=2x+4 so lets replace y with 2x+4 in the second equation
2x-y=6 Becomes ...
2x-(2x+4)=6
Solve for x

Answer 3

I think I got it it might be uh A)2,8 if I got it wrong thanks still for helping!

Answer 4

Following up from what Heart_Broken_Kid said, continue solving for x and see what happens.

Answer 5

Hmmm lets solve for x
2x-(2x+4)=6
2x-2x-4=6
0x-4=6
-4=6
-4 CAN NOT EQUAL 6
THIS IS FALSE

THEREFORE THERE IS NO SOLUTION
