4x plus 7 plus 3x equals 19 plus xx = 2
7.5
An equation where x equals 3.
(2, 3)
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
4x plus 7 plus 3x equals 19 plus xx = 2
if 3x+5=x+19 then x=7
X=2
7.5
An equation where x equals 3.
(2, 3)
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
x = 7
8x - 19 = 3x + 1 5x -19 = 1 5x = 20 x = 4
3x+7=19 3x=12 minus 7 from both sides x=4 divide by three on both sides leaving just what x equals
x=-6
1 + x + 2x = 20 So 1 + 3x = 20 so that 3x = 19 then x = 19/3 or 61/3
