x+3(x – 6) = -(x – 12) + 34

=> x + 3x – 18 = -x + 12 + 34

=> 4x – 18 = -x + 46

next add 18 on both sides

=> 4x = -x + 64

next add the x on both sides

=> 5x = 64

divide both sides by 5

=> x = 12.8

// times 3 with (x-6)

x +3x-18 = -x+12 + 34

// add x with 3x you will get 4x then

4x – 18 = -x + 46

// Group x at one side

4x + x = 46 +18

5x = 64

x = 64/5

x = 12.8

khrome_wind : 12 + 34 is 46 not 36

x+3(x-6) = -(x-12)+34

x+(3x-(3*6)) = (-x-(-12))+34

x+3x-18 = -x+12+34

4x-18 = -x+46

4x+x = 46+18

5x = 64

x = 9

hope that will be help.thanks.! BTW work hard bro.u will find math is interesting than u thought.!

distribute the negative on right side and then mulitply by 3 on left side

x + 3x – 18 = -x + 12 +34

combine like terms

4x – 18 = -x + 46

add x to both sides

5x – 18 = 46

add 18

5x = 64

x = 64/5

x+3x-18 = -(x – 12) + 34

x+3x = -(x – 12) + 52

4x = -(x – 12) + 52

4x = -x + 12 + 52

4x = -x + 64

3x = 64

x = 64/3

x = 21.333

x+3x-18=-x+12+34

4x-18=-x+36

4x=-x+58

5x=58

x=10.8

x+3x+-6=-(x-12)+43

4x+-6=(x-12)+43

6 6

4x=(x-12)+49

x x

5x=-12+49

5x=37

5 5

x+7.4
