Question

Super stuck on this.. any help would be great! Thanks

Determine the solution of the system.

y = x + 6
y = 2x

Answer 1

The idea here is to plug in y = 2x into the first equation, solve for x, then use it to find y.


y = x + 6

2x = x + 6

2x-x = 6

x = 6

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


y = x+6

y = 6+6

y = 12


So the solutions are x = 6 and y = 12 giving us the ordered pair (6,12)
