Answer:

The number is:

  • x=99.67

Step-by-step explanation:

Let 'x' be the number

  • 4.6 plus 1.9 times a number 'x' = 4.6 + 1.9x
  • Sum of number 'x' and 94.6 = x+94.6

Given that 4.6 plus 1.9 times a number equals the sum of the number and 94.6.

so the equation becomes

[tex]4.9+1.9x=x+94.6[/tex]

[tex]1.9x-x=94.6-4.9[/tex]

[tex]0.9x=89.7[/tex]

[tex]\mathrm{Multiply\:both\:sides\:by\:}10[/tex]

[tex]0.9x\cdot \:10=89.7\cdot \:10[/tex]

[tex]9x=897[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}9[/tex]

[tex]\frac{9x}{9}=\frac{897}{9}[/tex]

[tex]x=\frac{299}{3}[/tex]

[tex]x=99.67[/tex]

Therefore, the number is:

  • x=99.67
