Question

4. (a) 3x - 12 + 4x = 6x + 6​

Answer 1

Answer:

x = 18.

Step-by-step explanation:

Simplify LHS,

7x - 12 = 6x + 6

Subtract 6 from both sides to eliminate 6 from RHS,

7x - 12 - 6 = 6x

7x - 18 = 6x

Add 18 to both sides to eliminate 8 from LHS,

7x - 18 + 18 = 6x + 18

7x = 6x + 18

Subtract 6x from both sides to eliminate 6x from RHS,

7x - 6x = 18

x = 18

Therefore, final answer is x = 18.
