    just replace the x to 9-2(4x+5) so it will be 9-2 (4(-4)+5) like @agustin_pc put..

    −7x−3(9−7x)ifx=−2 since x is given, we replace the x to -2 -7(-2)-3(9-7(-2)) and we follow the PEMDAS which is parentheses first right, so -7(-2)-3(23) and same thing again -7(-2) is 14 -3(23) is -69 so its 14-69 and u finish it.. and i think thats how you do it.. or someone can check mine and if something is wrong just recheck it and thankz

    if x =7 -> 6(3(7)-1)-10(7), 6(21-1)-70, 6(20)-70, 120-70 = 50
