To solve the equation 6d - 3d + 2d = 35, we first combine like terms on the left side. This gives us 5d + 2d = 35. Combining like terms further, we get 7d = 35. To find the value of the unknown variable "d," we divide both sides by 7, resulting in d = 5.

To keep it balanced, whatever you do to one side of the equals, do to the other: 2d + 7 = 9 ⇒ 2d + 7 - 7 = 9 - 7 ⇒ 2d = 2 ⇒ 2d ÷ 2 = 2 ÷ 2 ⇒ d = 1
2d + 25 = 55Therefore 55 - 25 = 2dTherefore, 2d = 30d = 30/2Therefore, d = 15
4(9)-11=25 2(9)+7=25 d=9
