The answer is x=3 I am pretty sure
Answer:
0 = 0
Step-by-step explanation:
2(x+4) = 4x + 3 - 2x + 5
Distribute
2 ( x + 4 ) = 4x + 3 - 2x + 5
2x + 8 = 4x + 3 - 2x + 5
Add the numbers
2x + 8 = 4x + 3 - 2x + 5
2x + 8 = 4x + 8 - 2x
Combine like trems
2x + 8 = 4x + 8 - 2x
2x + 8 = 2x + 8
Subtract 8 from both sides of the equation
2x + 8 = 2x + 8
2x + 8 - 8 = 2x + 8 - 8
Simplify
Subtract the numbers
2x = 2x
Subtract 2x from both sides of the equation
2x = 2x
2x - 2x = 2x - 2x
Simplify
Combine like terms
0=0
Result
0 = 0
