3x-8.(-6)=4x+10
=> 3x - (-48 ) = 4x+10
=> 3x + 48 = 4x + 10
=> 48 - 10 = 4x - 3x
=> 38 = x
Vậy x = 38
\(3x-8.\left(-6\right)=4x+10\)
\(3x+48=4x+10\)
\(4x-3x=48-10\)
\(x=38\)
3x-8.(-6)=4x+10
=>3x+48=4x+10
=>-10+48=4x-3x
=>x=38
3x-8.(-6)=4x+10
=> 3x - (-48 ) = 4x+10
=> 3x + 48 = 4x + 10
=> 48 - 10 = 4x - 3x
=> 38 = x
Vậy x = 38
\(3x-8.\left(-6\right)=4x+10\)
\(3x+48=4x+10\)
\(4x-3x=48-10\)
\(x=38\)

giúp mình giải bài toán.......
1)3x-6=5x+2
2)15-x=4x-5
3)x-15=6+4x
4)-12+x=5x-20
5)7x-4=20+3x

7)x+15=20-4x
8)17-x=7-6x
9)-4|x-2|=-8
10)-7|x+4|=2.(-7)
Tìm x
1) 5x - 16 = 40 + x
2) 4x - 10 = 15 - x
3) 3x - 6 = 5x + 2
4) 15 - x = 4x - 5
5) x - 15 = 6 + 4x
6) -12 + x = 5x - 20
7) 7x - 4 = 20 + 3x
8) 5x - 7 = -21 - 2x
9) x + 15 = 20 - 4x
10) 17 - x = 7 - 6x
tìm x biết
