If you mean: 3x-(2x+4x-6) then 3x-2x-4x+6 simplifies to 6-3x
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
4x+7-3x = 15 4x-3x = 15-7 x = 8
3x+5 = 4x-10 In algebra, what you do to one side you do the other Now you add 10 to both sides 3x+5 + 10 = 4x-10+10 3x +15 = 4x now subtract 3x from both sides 3x-3x +15 = 4x-3x 15 = x
No, that's not correct.-3x + 4x = x
-1
It has no solution and if you mean 4x+10+3x+40-3x then it can be simplified to: 50+4x _________________________________________________________________________________________ Assuming that the equation is 4x+10+3x+40-3x = 0, then it will reduces to 4x = - 50, then the answer is: x = -12.5
3x+7=4x 7=4x-3x 7=x
3x+7=4x-73x=(-)7+4x-4x(-)1x=(-)7________(-)1x=7add (-3x) to each side of equation3x +7 = 4x-3x +3x +7 = 4x -3x0 +7= 1x7=x
If you mean: 3x-(2x+4x-6) then 3x-2x-4x+6 simplifies to 6-3x
3x = 7-4x 3x+4x = 7 7x = 7 x = 1
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
- 3X - (- 4X) is the same as - 3X + 4X X(- 3 + 4) that is all the factoring needed there
3x-3x+4x^2+8x=4x^2+8x
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
3x+5= 4x-10+10 +103x+15= 4x-3x -3x15=X
