Question

Solve for x =2.4x + 3.4=15.4

Answer 1

x = 5

Explanation:

`\mathrm{Multiply\:both\:sides\:by\:}10`

`2.4x\cdot \:10+3.4\cdot \:10=15.4\cdot \:10`

`\mathrm{Refine}`

`24x+34=154`

`\mathrm{Subtract\:}34\mathrm{\:from\:both\:sides}`

`24x+34-34=154-34`

`\mathrm{Simplify}`

`24x=120`

`\mathrm{Divide\:both\:sides\:by\:}24`

`(24x)/(24)=(120)/(24)`

x = 5

Answer 2

• 5

Explanation :

`\longrightarrow \qquad \sf{2.4x + 3.4=15.4}`

Subracting 3.4 from both sides we get :

`{\longrightarrow \qquad \sf{2.4x + 3.4 - 3.4=15.4 - 3.4}}`

`\longrightarrow \qquad \sf{2.4x =12}`

Dividing 2.4 from both sides we get :

`\longrightarrow \qquad \sf{ (2.4x)/(2.4) = (12)/(2.4) }`

`\longrightarrow \qquad \sf{ \frac{ \cancel{2.4} \: x}{ \cancel{2.4}} = 5 }`

`\longrightarrow \qquad \bf{x = 5 }`

Therefore,

• The value of x is 5.
