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 + 1.9xSum 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

4.9+1.9x=x+94.6

1.9x-x=94.6-4.9

0.9x=89.7

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

$0.9x\cdot \:10=89.7\cdot \:10$

9x=897

$\mathrm{Divide\:both\:sides\:by\:}9$

$\frac{9x}{9}=\frac{897}{9}$

$x=\frac{299}{3}$

x=99.67

Therefore, the number is:

x=99.67
