Linear equations. ​

Answer 1

Answer:

x = 101

Explanation:

4x + 5x + 90 = 999

9x + 90 = 999

9x = 999 - 90

9x = 909

x = 909/9 = 101

Answer 2

______________________________________

✧ Solution ↓

________________________________

➠ 4x + 5x + 90 = 999

➠ 9x + 90 = 999

➠ 9x = 999 - 90

➠ 9x = 909

➠ x = $\dfrac{909}{9}$

➠ x = 101

Therefore, value of x = 101
