Question

Which number or numbers from the set {14, 17,19} make the equation

Y-3=11+5 true?

Answer 1

To find out which number(s) from the set {14, 17, 19} satisfy the equation Y-3=11+5, we need to substitute each number into the equation and see if it holds true.

1. For 14:
Y-3 = 11 + 5
14 - 3 = 11 + 5
11 = 16
The equation is false for 14.

2. For 17:
Y-3 = 11 + 5
17 - 3 = 11 + 5
14 = 16
The equation is false for 17.

3. For 19:
Y-3 = 11 + 5
19 - 3 = 11 + 5
16 = 16
The equation is true for 19.

Therefore, the number 19 from the set {14, 17, 19} makes the equation Y-3=11+5 true.
