5.2 < x < 5.5
square
5.2² < x² < 5.5²
27.04 < x² < 30.25
Pick any number for between 27.04 and 30.25 for x², as long as it's not a perfect square. So you could pick 30.
x² = 30
x = √30 → irrational number between 5.2 and 5.5
Step-by-step explanation:
x = 7
3 + 4x = 5x - 4
3 + 4(7) = 5(7) - 4
3 + 28 = 35 - 4
31 = 31
