Question

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

Answer 1

Answer:

12 = x

Step-by-step 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
