-6x + y = - 4 / + 6x ;
y = 6x - 4 ;
We substitute y in first equation : -5x + 3( 6x - 4 ) = 12;
-5x + 18x - 12 = 12 ;
13x - 12 = 12 ;
13x = 24 ;
x = 24 / 13 ;
y = 6*(24 / 13 ) - 4 ;
y = 144 / 13 - 4 ;
y = 144 / 13 - 52 / 13;
y = 92 / 13 ;
The solution is x = 24 / 13 and y = 92 / 13 ;

Answer:
x = -8
y = 6
Step-by-step explanation:
x + 2y = 4
-x - y = 2
-8 + 2(6) = 4
-(-8) - 6 = 2
-8 + 12 = 4
8 - 6 = 2
Answer:
I dont know im really sorry
5 1/3+1 1/3
= 15/3+1/3 3/3+1/3
=20/3
= 18/3+2/3
=6 2/3
OR
when both fractions are the same, you can just add them this way:
5 1/3 + 1/3
= 5+1 + 1/3+1/3
=6+2/3
= 6 2/3
