Answer

All equations (A, B, C, D) have exactly one solution. Explanation 1. Simplify Equation A -13x + 12 = 13x - 13 \implies -26x = -25 \implies x = \frac{25}{26} (One solution) 2. Simplify Equation B 12x + 12 = 13x + 12 \implies -x = 0 \implies x = 0 (One solution) 3. Simplify Equation C -13x + 12 = 13x + 13 \implies -26x = 1 \implies x = -\frac{1}{26} (One solution) 4. Simplify Equation D 12x + 12 = 13x - 12 \implies -x = -24 \implies x = 24 (One solution)

Explanation

1. Simplify Equation A<br /> $-13x + 12 = 13x - 13 \implies -26x = -25 \implies x = \frac{25}{26}$ (One solution)<br /><br />2. Simplify Equation B<br /> $12x + 12 = 13x + 12 \implies -x = 0 \implies x = 0$ (One solution)<br /><br />3. Simplify Equation C<br /> $-13x + 12 = 13x + 13 \implies -26x = 1 \implies x = -\frac{1}{26}$ (One solution)<br /><br />4. Simplify Equation D<br /> $12x + 12 = 13x - 12 \implies -x = -24 \implies x = 24$ (One solution)
