1. When x = 1, the second power of MX minus 3x minus 4 is 0, then the value of M is 0______ 2. If the solution of equation one-third (x minus 4) minus 8 = negative half (x minus 2) is the same as that of equation 4x - (3a + 1) = 6x + 2a-1, find the value of one-third of equation A-A?

1, substituting M = 7 into the original equation, m-3-4 = 0, then M = 7.2, solving the equation by one-third (x minus 4) minus 8 = negative dichotomy (x minus 2) to get x = 12.4, substituting x = 12.4 into 4x - (3a + 1) = 6x + 2a-1, and finding a = - 4.96, one-third of A-A equals - 124 / 25 + 25 / 124

Add 2 to a number, subtract 2, multiply 2, divide 2, and then add these four results. The sum is 5.85. What's the number

Add 2 to a number, subtract 2, multiply 2, divide 2, and then add these four results. The sum is 5.85,
This number is (5.85-2 + 2) / (1 + 1 + 2 + 1 / 2) = 1.3
