Hi All, I don't use W|A that much, and I may be overlooking something simple. In MMA 11 the expression

values=Solve[{a==2*c,a+2*b==3*c+d,a==2*d,b==c},{a,b,c}]

is solved immediately. However, when I paste the same line into W|A, I get no solution, just the incomplete looking enter image description here

Can someone tell me what is happening here?

This

Solve[{a==2*c,a+2*b==3*c+d,a==2*d,b==c},{a,b,c}]

or even just this

{a==2*c, a+2*b==3*c+d, a==2*d, b==c}

WA link

appear to work.

Assignments to named variables, especially names of more than a single character, have been an issue in WA.

Got it. Thanks for the tip.
