You would multiply 6.2 by -4 which is -24.8 so then the equation is y+-24.8=-13 then add -24.8 to both sides and it will be y=11.8
-320. The negative sign represents loss. In all of the other cases, values are either being added or not changed at all.
Multiply the first equation by -2 gives:_
-2y = -8 + 2x
2y = 8 - 2x
adding these 2 equations:-
0 = 0
This shows that the 2 equations are equal so there are infinite solutions
