Question

Explain how you would solve the equation -7 + x = 12 using the properties of equality

Answer 1

x=19

Answer 2

-7+x=12
add 7 to the LHS.
Now, to balance the equality, add 7 to the right also.
it becomes
-7 + x +7 = 12 + 7
=>x+0=19
=> x=19.

Answer 3

add 7 to both sides

Answer 4

The property of equality that has been used is the property that say
if you add some thing to both sides of an equality then you will still have equality
