Question

Rewrite the equation below using ONLY the symmetric property of equality:2x + 5 = 3x -7

Answer 1

12 = x

Explanation:

Symmetry here would involve subtracting the same quantity from both sides of the equation.

Starting with 2x + 5 = 3x -7,

subtract 2x from both sides. This yields

5 = x - 7

Adding 7 to both sides yields

12 = x
