Mathematics
1 answer:
GarryVolchara [31]2 years ago
3 0

Answer:

x=-\frac{9}{4}

Step-by-step explanation:

<u>Step 1:  Subtract 21 from both sides</u>

8x + 21 = 3

8x + 21 - 21 = 3 - 21

8x = -18

<u>Step 2:  Divide 8 from both sides</u>

8x = -18

\frac{8x}{8}=-\frac{18}{8}

x=-\frac{9}{4}

Answer:  x=-\frac{9}{4}
