Answer :
Explanation :
[tex]\longrightarrow \qquad \sf{2.4x + 3.4=15.4}[/tex]
Subracting 3.4 from both sides we get :
[tex]{\longrightarrow \qquad \sf{2.4x + 3.4 - 3.4=15.4 - 3.4}}[/tex]
[tex]\longrightarrow \qquad \sf{2.4x =12}[/tex]
Dividing 2.4 from both sides we get :
[tex]\longrightarrow \qquad \sf{ \dfrac{2.4x}{2.4} = \dfrac{12}{2.4} }[/tex]
[tex]\longrightarrow \qquad \sf{ \dfrac{ \cancel{2.4} \: x}{ \cancel{2.4}} = 5 }[/tex]
[tex]\longrightarrow \qquad \bf{x = 5 } [/tex]
Therefore,
Answer:
x = 5
Step-by-step explanation:
[tex]\mathrm{Multiply\:both\:sides\:by\:}10[/tex]
[tex]2.4x\cdot \:10+3.4\cdot \:10=15.4\cdot \:10[/tex]
[tex]\mathrm{Refine}[/tex]
[tex]24x+34=154[/tex]
[tex]\mathrm{Subtract\:}34\mathrm{\:from\:both\:sides}[/tex]
[tex]24x+34-34=154-34[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]24x=120[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}24[/tex]
[tex]\frac{24x}{24}=\frac{120}{24}[/tex]
x = 5
