Answer 1

1) а) А = 120
b) B = 30
c) C = 160

2) a) 6(4+10m)+3(2-5m) = 24+60m+6-15m = 30+45m

b) 6(4+10m)+3(2-5m) = 120
30+45m = 120
45m = 120-30
45m = 90
m = 90:45
m = 2

Answer 2

№1
а) А(120); б) В(30); с) С(160).

№2
$a)6(4 + 10m) + 3(2 - 5m) = 24 + 60m + 6 - 15m = 30 + 45m$
$b) 30 + 45m = 120 \\ 45m = 120 - 30 \\ 45m = 90 \\ m = 2$
