Question

Solve 3a + 4 = 39 - 2a
a =.
...

Answer 1

3a+2a=39-4

5a=35

a=35\5

a=7

Answer 2

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
