The above linear equation is only true if x = 5 and hence the given linear equation has only one solution i.e. x = 5. Example 2: Consider the equation 9(x – 1) – 35 = 8x + 37. On solving we have 9x – 9 – 35 = 8x + 37. Collect the like terms on both sides by transferring them, we have. 9x – 8x = 37 + 35 + 9 = 80 which gives x = 80.
