Question 154061
What is x if x=2, x=x+5. Solve. I don't think it's possible, am I right?
.
The confusion here is you want to know the NEW value of {{{x}}} but you represent it as the same identity as {{{x}}} too.
To re-phrase the question (I'm not questioning your teacher):
What is {{{x[2]}}} if {{{x[1]=2}}} in eqn {{{x[2]=x[1]+5}}}?
Then you can solve it. Continuing,
{{{x[2]=2+5}}}
{{{x[2]=7}}} -----------> final answer
