Use substitution to solve the system. (If the system is dependent, use the parameters y and z as necessary. If the system is inconsistent, enter INCONSISTENT.)

2 1
-- y+ -- z = -1

1 2
-- y - -- z =7
3 5

(y,z) = ( , )

you didn't use my method

hero · Answer

Multiply both equations by 15 and see what happens

hero · Answer

Shannon, you there?

anonymous · Answer

yeah, so times 2/3 by 15 and 1/5 by 15?

hero · Answer

multiplying both by 15 should eliminate the denominators if you know how to do it

anonymous · Answer

so 2y + 1z =-1?

hero · Answer

No, it's not that simple

hero · Answer

You have to actually multiply each term by 15 then cancel and reduce:
