"x" would equal 1 because 7/1 is 7 minus 2 equals 5 and 3/1 is 3 plus or + 2 is 5.
If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A

2bc + 8b - 3c - 12 is an expression, not an equation or inequality. It cannot, therefore have "an answer".
2 minus 2/5 plus 1/2 minus 4 = -1.9
15x minus 8=minus 180 3x+8=24
The quadric equation is: negative b plus or minus the square root of b squared minus 4ac all over(divided by) 2a
x equals negative b plus or minus the square root of b squared minus 4bc over 2a
negative b plus or minus the square root of b minus 4 times ac all over 2 a
If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A
x=-1 ^ how do you know?

plus or minus. You see it often with square roots. The square root of 9 is plus or minus 3.
The plus-minus sign (±) can be used to imply plus or minus within a sum. For example, one equation reads:-b ± sqrt (b2 - 4ac)This refers to an equation with two possible solutions - that from which you use the plus sign, and that from which you use the minus sign.
2 minus 2/5 plus 1/2 minus 4 = -1.9
15x minus 8=minus 180 3x+8=24
It is an equation and the value of n is 9
