2.2 maybe? I would check with someone
C- elemination or reduction
Method of elimination or reduction
Adding two equations is to obtain a new equation whose right (left) member is the sum of the right (left) members of the equations that are added together.
<span> 7X+5y=19
-7X-2y=-16.
</span> Adding two equations
3y=3 ---> y=1
then
7x+5(1)=19
7x=19-5
x=14/7=2
The solution is not the ones in the parenthesis.
your solution is, (0,16)
