The solution for x is 3.
Since 3 is to 10
as 2x is to 20
Then the ratio holds:
3 / 10 = 2x / 20
Solving for x:
3 / 10 = 2x / 20
0.3 = x/10
(0.3 * 10) = x
3 = x
x = 3
2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.
(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4
Here are possibilities of what you mean: a: (3-2)(x-2)=10 Solution: (3-2)(x-2)=10 1(x-2)=10 x-2=10/1 x=10+2=12 b: 3-2(x-2)=10 Solution: 3-2(x-2)=10 3-10=2(x-2) -7=2x-4 -3=2x x=-3/2=-1.5
2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
2x-3 = 17 2x = 17+3 2x = 20 x = 10
2x+17 = 4x-3 2x-4x = -3-17 -2x = -20 Answer: x =10
If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.
(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4
4 - 2x = 10 -2x = 10-4 -2x = 6 -x = 3 x = -3
3-2x-2 = 10 -2x = 10+2-3 -2x = 9 x = -4.5

2 is a solution of the equation, but not if it's an inequality.
Let's call the number "x". The given equation can be translated as: x * 3 = 2 * (x + 5). Simplifying the equation, we have: 3x = 2x + 10. Subtracting 2x from both sides gives: x = 10. So the solution to the equation is x = 10.
