Step 1 (6x+2y)+(4x-3y)

Step 2 remove brackets (Note* If there was a subtraction sign separating the two then you have to multiply the (-) in. For example (6x+2y)-(4x-3y) so you have to multiply (-) in to (4x-3y) which becomes -4x+3y.)

Step 3 Now after you removed the brackets it becomes 6x+2y+4x-3y Now, collect the like terms ( this means that you have to add/subtract but in this question you add the terms which are alike. So, 6x+2y+4x-3y= 6x+4x+2y-3y

Step 4 Now simplify it. so 6x+4x+2y-3y= 10x-1y

There you go, that's the answer!

ok - there are somewhat some right here, so i ought to bypass astep or 2. enable's bypass 21. 15 - 2y = 3y 15 = 3y+2y 15 =5y 5=y 22. 2p - 9 = 5p + 12 2p =5p +21 -3p = 21 p = -7 23.5x - sixteen = 14 - 5x 5x = 30-5x 10x = 30 x =3 24. -3g + 9 = 15g - 9 -3g=15g -18 -18g = -18 g=a million 25. 11x - 21 = 17 - 8x 11x = 38-8x 19x = 38 x =2 26. 4x + 27 = 3x + 34 4x = 3x +7 x=7 27. 5x - 4x = -6 + 3 x = -3 28.10x = 2y - 6y + 7 10x = -4y+7 (completed) 29. r - 2 + 3r = 6 + 5r 4r-2=6+5r -r =8 r= -8 30. 4 + 6x - 9x = 3x 4-3x =3x 4 = 6x 2/3 =x 31. 2t - 3t + 8 = 3t - 8 -t+8=3t-8 -4t = -sixteen t=4 32. 13x + 8 + 8x = -9x - 22 21x+8 = -9x -22 30x = -30 x= -a million 33. -x + 6 - 5x = 14 - 2x -6x +6 = 14 -2x -4x = 8 x= -2 34. 5x - 3x + 4 = 3x + 8 2x+4 = 3x +8 -x = 4 x= -4 i'm going to bypass away you to do the exams. wish this facilitates.

6x + 2y + 4x - 3y
6x + 4x + 2y - 3y
10x - y
2008-06-26 4:20 pm
6x+2y+4x+3y
(6x+4x)+(2y-3y)
10x+(-1y)
2008-06-26 4:17 pm
(6x + 2y) + (4x - 3y)
= 6x + 2y + 4x - 3y
= 6x + 4x + 2y - 3y
= 10x - y

(6x+2y)+(4x-3y)
6x+4x=10x
2y+-3y=-y
The parenthesis are not necessary. Drop them and combine the like expressions. This is what you have left.
10x-y

learn it yourself dude
2008-06-26 4:10 pm
6x+2y+4x-3y
10x-y
2008-06-26 4:06 pm
The brackets are unnecessary so:

6x+2y+4x-3y simplifies to 10x-y

But there is nothing to solve - just simplify
