4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
16x+9 without the rest of the equation, what this equals, I can't solve
6x + 3 = 2x + 5 4x = 2 x=1/2
2x + 6 - 6x = 30= 6 - 4x = 30= -4x = 24= 4x = -24= x = -6
Add 12 to each side: 4x + 6x = 20 ie 10x = 20 so x = 2
-2x + 11 + 6x = 4x + 11
6x + 34 = 4x +284 6x - 4x = 284 - 34 2x = 250 x = 125
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
11 + 4x
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
4x+6y=62 -6x+6y=-18 what is the ordered pair
6x + 10 + 4x = 5010x + 10 = 5010x = 40x = 4
6x-52 = 4x+40 6x-4x = 40+52 2x = 92 Answer: x = 46
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
4x-15=6x-4x 4x-22.4=2x 2x=22.4 x=11.2
X equals to 8
11 + 6x = 2x - 13 Subtract 2x from both sides: 11 + 4x = -13 Subtract 11 from both sides: 4x = -24 Divide both sides by 4: x = -6
