Use properties to rewrite the given equation. Which equations have the same solution as 3/5x +2/3 + x = 1/2 –1/5x? Check all that apply.
8/5x +2/3 = 1/2 – 1/5x
18x + 20 + 30x = 15 – 6x
18x + 20 + x = 15 – 6x
24x + 30x = –5
12x + 30x = –5

Answer:
Step-by-step explanation:
3/5x +2/3 + x = 1/2 –1/5x
Adding 3/5x & x on LHS
8/5x + 2/3 = 1/2 - 1/5x
Multiplying by 30 on both sides
18x + 20 + 30x = 15 - 6x
adding 6x both sides & subtracting 20 both sides
18x + 20 + 30x + 6x - 20 = 15 - 6x + 6x - 20
Cancelling 20 & -20 on left side & 6x & -6x on RHS
18 x + 6x + 30x = 15 - 20
24 x + 30x = -5
18x + 20 + x = 15 – 6x - Incorrect
12x + 30x = –5 - Incorrect
