Answer:
An equivalent equation would be 2x = 4.
Explanation:
Expanding the brackets and simplifying, we get:
8x + 4 - 3x + 6 = 20
Combining like terms, we get:
5x + 10 = 20
Subtracting 10 from both sides, we get:
5x = 10
Dividing both sides by 5, we get:
x = 2
So an equivalent equation would be 2x = 4.
