Question


6 (x + 3) − 37 - Simplify the left side of the equaiton
6 x + 18 − 37 - 6*x and 6*3
6 x − 19 = x + 6

6 x − 19 − x = 6 - move x to the left side of the equation by subtracting from both sides
5 x − 19 = 6 - subtract x from 6x
5 x = 6 + 19 - Move 19 to the right side of the equation by adding 19 to both sides
5 x = 25 - Add 6+19
25
x = - Move 5 to the right side by dividing by 5
5

x = 5

Apply standard algebraic properties.


6 (x + 3) − 37 = x + 6



6x + 18 − 37 = x + 6 Apply the distributive property.

6x − 19 = x + 6 Combine like terms.

5x = 25 Place x - terms on one side and simplify.
25
x = Multiply both sides by 1
, the reciprocal of 5.
