Question 1049088
How do you want to solve them? Solve for a variable and substitute into other equation, and use value to find other variable.


{{{5x=-2y-1}}}
{{{x=-(2y+1)/5}}}
-
{{{3(-(2y+1)/5)+7y=11}}}
{{{-3(2y+1)+35y=55}}}
{{{-6y-3+35y=55}}}
{{{29y=55+3}}}
{{{29y=58}}}
{{{highlight(y=2)}}}



Now, what is x?
{{{x=-(2*2+1)/5}}}
{{{highlight(x=-1)}}}
