If the square of 3a of 2x - 2 + 1 = 0 is a linear equation with one variable, then a= Given the square of | 2x + 1 | + (2 / 1y-1) = 0, find the value of the square of the cube Y-3 / 1X of the algebraic formula 2x

If the square of 3a of 2x - 2 + 1 = 0 is a linear equation with one variable, then a= Given the square of | 2x + 1 | + (2 / 1y-1) = 0, find the value of the square of the cube Y-3 / 1X of the algebraic formula 2x

A = 1 / 3 or - 1 / 3
Because | 2x + 1 | + (1 / 2y-1) ^ 2 = 0 and | 2x + 1 | > = 0 (1 / 2y-1) ^ 2 > = 0
So 2x + 1 = 0 1 / 2y-1 = 0
So x = - 1 / 2, y = 2
So 2x ^ 3y-1 / 3x ^ 2Y ^ 2 = x ^ 2Y (2x-1 / 3Y) = - 1 / 2) ^ 2x (- 2x1 / 2-1 / 3x2) = - 5 / 6
