1. x - 4 = 10
Sol.
x - 4 = 10
Add 4 to both sides of the equation:
x = 14
The answer is x = 14
Check the solution by substituting 14 in the original equation for x. If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer.
2. 2x - 4 = 10
Sol.Divide both sides by 2:

The answer is x = 7.
Check the solution by substituting 7 in the original equation for x. If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer.
* 2(7) - 4 = 14 - 4 = 10.
3 5x - 6 = 3x - 8
Sol. 5 x - 6 = 3 x - 8
Subtract 3x from both sides of the equation:

The answer is x = - 1
Check the solution by substituting -1 in the original equation for x. If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer.
* Left side: 5(-1) - 6 = - 11
* Right side: 3(-1) - 8 = - 11
