Question

x+3y=7
2x+2y=6
solve...
please help

Answer 1

x=-1
y=-2

Answer 2

x+3y=7 ---->A
2x+2y=6---->B

from A we have
x = 7-3y
put this in B
2(7-3y) +2y =6
solve this now

Answer 3

\[x+3y=7[1]\]
\[2x+2y=6[2]\]
\[[1]\]
\[x=7-3y\]
\[[2]\]
\[2(7-3y)+2y=6\]
\[14-6y+2y=6\]
\[14-4y=6\]
Make y the subject and solve.
