Hello! And thank you for your question!
First subtract 4x from both sides:
-6 = 10x - 3 - 4x
Then Simplify 10x - 3 -4x:
-6 = 6x - 3
Then add 3 to both sides:
-6 + 3 = 6x
After that simplify again of 3 + (-6):
6x = -3
Divide both sides by 6:
-3.6 = x
Simplify once more of 3/6:
-1/2 = x
Final Answer:
x = -1/2
