Answer 2

Step-by-step explanation:

a] 7x + 2x = 1575

a] 7x + 2x = 1575 9x = 1575

a] 7x + 2x = 1575 9x = 1575 x = 1575 ÷9

a] 7x + 2x = 1575 9x = 1575 x = 1575 ÷9x=175

a] 7x + 2x = 1575 9x = 1575 x = 1575 ÷9x=175 Kamal = 7x

a] 7x + 2x = 1575 9x = 1575 x = 1575 ÷9x=175 Kamal = 7x 7×175 = 1225

a] 7x + 2x = 1575 9x = 1575 x = 1575 ÷9x=175 Kamal = 7x 7×175 = 1225 Madhu = 2x

a] 7x + 2x = 1575 9x = 1575 x = 1575 ÷9x=175 Kamal = 7x 7×175 = 1225 Madhu = 2x2 ×175 = 350

b] 3x+ 5x +7x =3450

15x = 3450

x = 3450÷15

x= 230

A = 3×230 = 690

B = 5×230 = 1150

C= 7×230 = 1610
