Answer:

x = -5

Step-by-step explanation:

2x + 10 = 3x + 15      Distribute

2x + 10 - 15 = 3x + 15 - 15      On our way to isolate x

2x - 5 = 3x + 0      Simplifying

- 5 + 2x - 2x = 3x - 2x      Isolating x

- 5 = 1x      Simplifying

x = - 5      Answer
2x+10=3(x+5)

1. 3(x+5) = 3x+15 (expanding brackets)
So it would be 2x+10 = 3x+15
2. 2x+10-10= 3x+15-10 (subtract 10 from both sides)
So it would be 2x= 3x+5
3. 2x-3= 3x+5-3x (subtract 3x from both sides)
So it would be -x= 5
4. -x/-1= 5/-1 (divide by negative 1 to make x positive)
So it would be x= -5

Answer is = x=-5
