To evaluate the expression x + 5y when y = 4 and x = 6, we substitute the given values into the expression and simplify.
Substituting y = 4 and x = 6 into the expression x + 5y, we get:
6 + 5(4)
Simplifying further:
6 + 20 = 26
Therefore, when y = 4 and x = 6, the expression x + 5y evaluates to 26.
Please note that this is the specific numerical answer when y = 4 and x = 6.
