Answer:

a = 7

Explanation:

Given equation,

  • 3a + 4 = 39 - 2a

Move all terms containing 'a' to the left side of the equation and others to the right side.

  • 3a + 2a = 39 - 4

Calculate the sum and difference,

  • 5a = 35

Dividing both sides of the equation by 5,

  • 5a/5 = 35/5
  • a = 7

Hence, a = 7
