LINEAR EQUATIONS' EXAMPLES

Solving example No 1:
find x if 2x + 4 = 10

steps to solve 2x + 4 = 10

1.Isolate "x" to one side of the equation by subtracting 4 from both sides:
2x + 4 - 4 = 10 - 4
2x = 6

2.Divide both sides by 2:
2x / 2 = 6 / 2
x = 3

3.Check your work with the original equation:
2x + 4 = 10
2(3) + 4 = 10
6 + 4 = 10

Solving example #2: find x if 3x - 4 = -10
steps to solve 3x - 4 = -10

1.Isolate "x" to one side of the equation by adding 4 to both sides:
3x - 4 + 4 = -10 + 4
3x = -6

2.Divide both sides by 3:
3x / 3 = -6 / 3
x = -2

3.Check your work with the original equation:
3(-2) - 4 = -10
-6 - 4 = -10
