Question

Four more than seven times a numbetis the same as twenty less than three times the number​

Answer 1

The Number is: 1.6

Explanation:

Let n = the number.

Seven times the number plus four equals twenty minus three times the number:

7n + 4 = 20 - 3n

10n = 16

n = 1.6, the number is 1.6

Proof:

7(1.6) + 4 = 20 - 3(1.6)

11.2 + 4 = 20 - 4.8

15.2 = 15.2

Hope this helps! Have an Awesome Day!! :-)
