To solve the first equation, we first simplify each side to get:
8x - 16 = 8x - 16 - 3x
8x - 16 = 8x - 16 - 3x
8x - 16 = 5x - 16
Next, we collect like terms and solve for x:
8x - 5x = -16 + 16
3x = 0
x = 0
Therefore, the solution to the first equation is x = 0.
To solve the second equation, we first subtract 1 from both sides to isolate the fraction:
1/2x = 3
Next, we multiply both sides by 2 to get rid of the fraction:
x = 6
Therefore, the solution to the second equation is x = 6.
