online Pre Algebra

Let us learn about online Pre Algebra

-->Solve the equation for x, 2(6x - 68) = 69. Solution:
2(6x - 68) = 69 (multiply 6 within the parenthesis)
(2 6x) – (2 68) = 69
12x – 136 = 69 add both sides by 136
12x - 136 + 136 = 69 + 136
12x = 205 divide both side by 12
12x/12 = 205/12
x = 17.08
