4x - 3x + 9 - 15 = 45

x - 6 = 45

  • Add 6 to both sides

x = 45 + 6

x = 51

Answer:


\sf \: x = 51

Explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 4x + 9 - 3x - 15 = 45

Then the value of x will be,

→ 4x + 9 - 3x - 15 = 45

→ (4x - 3x) + (9 - 15) = 45

→ (x) + (-6) = 45

→ x - 6 = 45

→ x = 45 + 6

→ [ x = 51 ]

Hence, the value of x is 51.
