Question

Item 12

Solve the system of linear equations by substitution.


y−x=0

2x−5y=9

Answer 1

If I’m correct you multiply add 5y to the -5y which gives you 2x=14 since you have to add the 5y to the 9, then you proceed to divide 2x with 14 which gives you 7 so the system of the equation is 7

Answer 2

The answer should be 0.9
