Hello,
Because there is no root of that function in the interval c(0, 10). Just
like the error message says.

I don’t believe this.
The error message says it all.
5*0-55 == -55
5*10-55 == -5

Readers,
The function 'solve' states that it is applicable to a vector or matrix
object.
Please what is the syntax to solve a very simple equation like:
5x + 1 = 56
The books read so far give explanations for simultaneous linear
equations or differential equations, but there have not been
Hello,
Try ?uniroot instead.
Your equation is equivalent to 5x - 55 = 0, so the instruction would be
uniroot(function(x) 5*x - 55, c(0, 20))
Hope this helps,
