To solve each equation, we need to isolate the variable by performing the necessary operations.

First, let's combine the x terms by moving all x terms to one side of the equation.

10 - 3x + 3x = 2x - 15 + 3x
10 = 5x - 15

Next, add 15 to both sides to isolate the x term.

10 + 15 = 5x - 15 + 15
25 = 5x

Now, to find the value of x, divide by 5 on both sides.

25/5 = 5x/5
5 = x

Therefore, x = 5

Combine the x terms by moving all x terms to one side of the equation.

10x - 8x = -9 - 7
2x = -16

Now, divide by 2 on both sides to isolate the x term.

2x/2 = -16/2
x = -8

Therefore, x = -8

First, combine all x terms by moving them to one side of the equation.

53 - 6x + 6x = 4x - 17 + 6x
53 = 10x - 17

Next, add 17 to both sides to isolate the x term.

53 + 17 = 10x - 17 - 17
70 = 10x

Now, divide by 10 on both sides to isolate the x term.

70/10 = 10x/10
7 = x

Therefore, x = 7
