4x plus 7 plus 3x equals 19 plus xx = 2
3x-7 = 14x-29 29-7 = 14x-3x 22 = 11x x = 2 Hope that helps!!;)
3x+7=4x 7=4x-3x 7=x
3x+7=37 -7 -7 3x=30 /3 /3 x=10
3x + 2y = 7
In the equation 3x plus 7 equals 13, x is equal to 2.
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
3x + 7 = -4x + 28 implies 7x + 7 = 28
If: 3x+7 = -14 Then: x = -7
3x - 8 = 7 so x = 5
3x-2y-7=0
If: 3x-7+x = 5 Then: x = 3
