The given expression is
[tex]2(1-3y)-13x[/tex]The value of x is 4
The value of y is -9
Substitute x by 4 and y by -9 in the expression above
[tex]2(1-3\lbrack-9\rbrack)-13(4)[/tex]We will multiply -3 by -9 first
[tex]2(1+29)-13(4)[/tex]Multiply -13 by 4
[tex]2(1+29)-52[/tex]Add 1 and 29, then multiply the answer by 2
[tex]\begin{gathered} 2(30)-52= \\ 60-52 \end{gathered}[/tex]Subtract 52 from 60
[tex]60-52=8[/tex]The value of the expression is 8
