3x + 6 = x - 10; subtract (x + 6) from each side to result in 2x = - 16; divide each side by 2 to result in x = -8.
10 -3x+8x = 25 -3x+8x = 25-10 5x = 15 x = 3
If: 3x-7 = 5x+13 Then: x = -10
(2, -1)
x=10
3x + 2 = -10 3x = -12 x = -4
In the equation 3x plus 7 equals 13, x is equal to 2.
2x+10=9+11-3x2x+10=20-3x5x+10=205x=10x=2
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
