1.(x+3)*2=18 2.(x-7)*4=64 3.(x-9)/2=25 4.(x+5)/7=8 5.(x-11)*6=84 6.(8x+3)/7=5

1) (x+3) * 2 = 18 2x (это квадрат) + 6 = 18 2x=18-6 2x=12 x=6 2) (x-7)*4=64 2x-28=64 2x=64+28 2x=92 x=46 3) (x-9)/2=25 x-9=50 x=50+9 x=59 4) (x+5)/7=8 x+5= 7*8 x+5=56 x=56-5 x=51 5) (x-11)*6=84 Сорян не знаю 6) (8x+3)/7=5 8x+3=35 8x=35-3 8x=32 x=4
