a = -7

Step-by-step explanation;

-5 ( 8a + 1 ) + 6 = 281

Step 1 :- Distribute -5 through parantheses.

  • -5 × 8a + 5 × 1 + 6 = 281
  • -40a - 5 + 6 = 281

Step 2 :- Combine like terms.

  • -40a + 1 = 281

Step 3 :- Move constant to right-hand side and change their sign.

  • -40a = 281 - 1

Step 4 :- Subtract the numbers.

  • -40a = 280

Step 5 :- Divie both side by -40 .

  • -40a / -40 = 280 / -40
  • a = -7
