Answer:

8x+5

Step-by-step explanation:

To solve this, you need to combine the like terms. The line terms are 3x +5x and -2+7. 3x+5x=8x and 7-2 (same thing as -2+7) is positive 5 so its 8x+5

simplified: 8x+5
you have to combine like terms so 3x+5x =8x because plus and minus equal plus and -2+5 equals 5 cause you subtract 2 from 7 since 2 is negative
