Question

2.x-138=2³.3²

Answer 1

\(2.x-138=2^3.3^2\)
\(\Rightarrow2.x-138=8.9\)
\(2.x=72\)
\(\Rightarrow2.x=72+138\)
\(2.x=210\)
\(\Rightarrow x=210\div2\)
\(\Rightarrow x=105\)

Answer 2

2.x-138=72

2.x=72+138

2.x=210

x=105

Answer 3

2.x -138 = 2³.3²

=> 2.x - 138 = 8.9 = 72 

=> 2.x = 72 + 138 = 210

=> x = 210 : 2

=> x = 105 

Answer 4

2.x-138=72

2.x      =138+72

2.x       =210

x          =210/2

x          =105

Answer 5

x=105

x=105

x=105

x=105

x=105

Answer 6

x = 105
