Given :
[tex]{\qquad { \longrightarrow \sf 4.5x - 2.9 = 1.2x }} [/tex]
To Find :
- The value of x.
Solution :
[tex]{\qquad { \longrightarrow \sf 4.5x - 2.9 = 1.2x }}[/tex]
Adding (2.9) to both sides we get :
[tex]{\qquad { \longrightarrow \sf 4.5x - 2.9 + 2.9= 1.2x + 2.9 }}[/tex]
[tex]{\qquad { \longrightarrow \sf 4.5x \: \: \cancel{ - \: 2.9} \: \: \cancel {+ \: 2.9}= 1.2x + 2.9 }}[/tex]
[tex]{\qquad { \longrightarrow \sf 4.5x = 1.2x + 2.9 }}[/tex]
Subtracting (-1.2x) from both sides we get :
[tex]{\qquad { \longrightarrow \sf 4.5x - 1.2x= 1.2x - 1.2x + 2.9 }}[/tex]
[tex]{\qquad { \longrightarrow \sf 3.3x= \cancel{1.2x} \: \: \cancel{ - \: 1.2x} + 2.9 }}[/tex]
[tex]{\qquad { \longrightarrow \sf 3.3x = 2.9 }}[/tex]
[tex]{\qquad { \longrightarrow \bf x = \dfrac{2.9}{3.3} }}[/tex]
