What is the value of x in the equation 6(x + 1) – 5x = 8 + 2(x – 1)?

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Write the sine and cosine values of a, b, respectively, in the figure for (1) and (2) + explanation.
