Answer:
The Number is: 1.6
Step-by-step 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!! :-)
