Question

x + 120 = 240

9x + 3 = 102

Answer 1

\(x+120=240\)

\(x=240-120\)

\(x=120\)

\(9x+3=102\)

\(9x=102-3\)

\(9x=99\)

\(x=99\div9\)

\(x=11\)

Answer 2

x + 120 = 240
x = 240 - 120
x = 120
 

9x + 3 = 102
9x = 102 - 3
9x = 99
x = 99 : 9
x = 11

x + 120 = 240
x = 240 - 120
x = 120
 

9x + 3 = 102
9x = 102 - 3
9x = 99
x = 99 : 9
​x = 11

Answer 3

\(x+120=240\)

            \(x=240-120\)

            \(x=120\)

\(9x+3=102\)

          \(9x=102-3\)

           \(9x=99\)

                \(x=99:9\)

                 \(x=11\)

Answer 4

x 9       =120-3

x9        =117

x         =117.9

x         =1053
