Answer 2

1) 6x + 18 = 0

To solve for x, we need to isolate it on one side of the equation.

First, we can subtract 18 from both sides to get:

6x = -18

Next, we divide both sides by 6 to solve for x:

x = -3

Therefore, the solution to the equation is x = -3.

2) 5x - 3 = 0

To solve for x, we need to isolate it on one side of the equation.

First, we can add 3 to both sides to get:

5x = 3

Next, we divide both sides by 5 to solve for x:

x = 3/5

Therefore, the solution to the equation is x = 3/5.

3) 4x - 7 = 0

To solve for x, we need to isolate it on one side of the equation.

First, we can add 7 to both sides to get:

4x = 7

Next, we divide both sides by 4 to solve for x:

x = 7/4

Therefore, the solution to the equation is x = 7/4.

4) -5x + 6 = 0

To solve for x, we need to isolate it on one side of the equation.

First, we can subtract 6 from both sides to get:

-5x = -6

Next, we divide both sides by -5 to solve for x:

x = -6/-5

x = 6/5

Therefore, the solution to the equation is x = 6/5.

5) 4x + 10 = -10

To solve for x, we need to isolate it on one side of the equation.

First, we can subtract 10 from both sides to get:

4x = -20

Next, we divide both sides by 4 to solve for x:

x = -20/4

x = -5

Therefore, the solution to the equation is x = -5.

6) 10x + 1 = 6x

To solve for x, we need to isolate it on one side of the equation.

First, we can subtract 6x from both sides to get:

4x + 1 = 0

Next, we subtract 1 from both sides to get:

4x = -1

Next, we divide both sides by 4 to solve for x:

x = -1/4

Therefore, the solution to the equation is x = -1/4.
