what are you choices for your problem
OpenStudy (anonymous):
no choices

slope = MX+B are you in slope?
OpenStudy (anonymous):
it should give you choices

The solution is \[x=6\] and \[y=12\] To find this, multiply the second equation by \[-1\] Then add the two equations. This gets rid of the \[y\] Solve for \[x\] and then sub this value into one of the equations to determine \[y\]

like point slope which i know it isn't, slope intercept form, slope

Alternatively, instead of using elimination, the above method, You can use Substitution. Given y = x +6. Substitute this for y in the next equation.
(x+6) = 2x. Solve for x. 6 = x
now plug back in to find y. y = x+6. so y = 6+6. y = 12. Therefore we have (6,12) as the solution
