7*(3x - 5) = 2x + 1/2
7 × (3x) + 7 × (- 5) = 2x + 1/2
21x - 35 = 2x + 1/2
Now you can add 35 to both sides of the equation:
21x - 35 + 35 = 2x + 1/2 + 35
21x = 2x + 1/2 + 35
Now you can subtract 2x from both sides of the equation:
21x - 2x = 2x - 2x + 1/2 + 35
19x = 1/2 + 35
Now you can multiply both sides of the equation by 2 to get rid of the fraction:
(19x)×2 = (1/2)×2 + 35×2
38x = 1 + 70 = 71
Now you can divid both sides of the equation by 38 to get 'x' on it's own:
(38x)/38 = 71/38
x = 71/38 This is the final answer.
