8. first do everything to get get x alone on its own side by subtracting or adding, for step two you take anything that is times x and divide it by the other side to get the answer for x. You should plug x into the original equation to check your answer.
Step-by-step explanation:
3. add 23 to both sides x=4. B
4. multiply the bottom number by the 5 which gives you 25 A
5. subtract 6 from both sides and divide by 3 which gives you 5
6. add 9 to both sides and divide by 7 so x = 6
7. subtract seven and you get x= 21
