Question

1)55-8x=7 2)27:y+29=38 3) (t-25):20=9 4)6*(18-k)=54

Answer 1

$55-8x=7 8x=55-7 8x=48 x=48:8 x=6 27:y+29=38 27:y=38-29 27:y=9 y=27:9 y=3 (t-25):20=9 (t-25)=20*9 t-25=180 t=180+25 t=205 6*(18-k)=54 (18-k)=54:6 18-k=9 k=18-9 k=9$

Answer 2

55-8х=7
8х=55-7
8х=48
х=48:8
х=6

27:у+29=38
27:у=38-29
27:у=9
у=27:9
У=3

(т-25):20=9
т-25=20*9
т-25=180
т=180+25
т=205

6*(18-к)=54
18-к=54:6
18-к=9
к=18-9
к=9
