Answer 1

=> 3x-7+5-x=10

=> 2x-2 = 10

=> 2x = 10+2 = 12

=> x = 12 : 2 = 6

Vậy x = 6

Tk mk nha 

Answer 2

(3x-7)-(-5+x)=10

3x-7+5-x=10

3x-x-7+5=10

2x-2=10

2x=10+2

2x=12x

x=12:2

x+6

Vật x=6

Answer 3

\(\left(3x-7\right)-\left(-5+x\right)=10\)

\(3x-7-5-x=10\)

\(2x=10+12\)

\(2x=22\)

\(x=11\)

vậy \(x=11\)
