Answer 1

Answer:

x = 80

Step-by-step explanation:

2x+30+4x+15+5x+25+7x+10=1520

18x+80=1520

18x=1520-80=1440

x=1440÷18=80

Answer 2

Answer: hello friend

first add  all the x values =

2+4+5+7=18x

then add all the other values  in the brackets

10+15+25+30=80

then add both the values

18x+80=1520

now transpose 80 to LHS

18x=1520-80

18x=1440

transpose18 to LHS

x=1440/18

on dividing we get x = 80
