Given :


{\qquad { \longrightarrow \sf 4.5x - 2.9 = 1.2x }}

To Find :

  • The value of x.

Solution :


{\qquad { \longrightarrow \sf 4.5x - 2.9 = 1.2x }}

Adding (2.9) to both sides we get :


{\qquad { \longrightarrow \sf 4.5x - 2.9 + 2.9= 1.2x + 2.9 }}


{\qquad { \longrightarrow \sf 4.5x \: \: \cancel{ - \: 2.9} \: \: \cancel {+ \: 2.9}= 1.2x + 2.9 }}


{\qquad { \longrightarrow \sf 4.5x = 1.2x + 2.9 }}

Subtracting (-1.2x) from both sides we get :


{\qquad { \longrightarrow \sf 4.5x - 1.2x= 1.2x - 1.2x + 2.9 }}


{\qquad { \longrightarrow \sf 3.3x= \cancel{1.2x} \: \: \cancel{ - \: 1.2x} + 2.9 }}


{\qquad { \longrightarrow \sf 3.3x = 2.9 }}


{\qquad { \longrightarrow \bf x = (2.9)/(3.3) }}
