1. 4d/2 - 3d = 2d - 3d = -d, not d nor 1 !!!!
2. 4d/2 - 3d = 1 2d - 3d = 1 -d = 1 d = -1
3. 4d/2=3d+1 4d=6d+2 -2d=2 d= -1
4. Did you mean 4d/(2 - 3d) = 1? If so, here: (2 - 3d)(4d/(2 - 3d) = 1) 4d= 2 - 3d 7d = 2 d = 2/7 Or, did you mean (4d/2) - 3d = 1? If so, here: 2d - 3d = 1 -d = 1 d = -1
5. 4d/2 - 3d = 1 Simplify first term by dividing 2 into 4: 2d - 3d = 1 Factorise out d: (2 - 3)d = 1 Subtract 3 from 2 to get -1: -d = 1 Multiply by -1: d = -1.
6. 4d/2 - 3d = 1 2d - 3d = 1 -d = -1 d = -1
7. If this is (4d/2) - 3d = 1, and not something like 4d/(2-3d) = 1, then: Simplify the first term (4d/2) - 3d = 1 2d - 3d = 1 Combine like terms on the left -d = 1 Multiply both sides by -1 d = -1
8. Hey there! Here's the answer. 4d/2-3d=1 --> Write the problem. 2d-3d=1 --> Divide 2 into 4d. -d=1 --> Subtract 3d from 2d. d=-1 Divide both sides of the equation by -1. So the answer is d=-1. Hope it helps!
9. 4d/2 - 3d = 1 multiply everything by 2 = 4d - 6d = 2 -2d = 2 d = -1
10. 2(4d/2-3d) = 2(1) or 4d-6d = 2 -2d = 2 (-2d) / -2 = (2) / -2 or d = -1
