Answer:
Step-by-step explanation:
7x + 3y = 6
7x = 6 - 3y
x = ( 6- 3y)/7
then we replace x in the second equation by (6-3y)/7
so 2 [(6-3y)/7] -5y =27
(12-6y)/7 -5y =27
(12- 6y -35y)/7 =27
12- 41y = 27x7
-41y = 189- 12
y = 177/ (-41)
y =-177/41
<sorry hun my eng ain't good>
we replace y by its valeur in the first equation
7x -531/41 =6
7x =6 + 531/41
7x =(246+531)/41
7x = 777/41
x= 111/41
soo yeah :)
