If 3x+6=19 then 3x=13 is true by which property?
find m<KLM if m<KLM=20x + 10, m<FLM=150, and m<KLF=2x+4
To determine which property is being used to justify the statement "3x = 13," let's first solve the given equation: 3x + 6 = 19.
To isolate the variable term, we need to subtract 6 from both sides of the equation:
3x + 6 - 6 = 19 - 6
3x = 13.
Now, we have found that 3x = 13.
The property being used here is the Subtraction Property of Equality. According to this property, if you subtract the same value from both sides of an equation, the equation remains balanced and true.
In this case, the subtraction property is used when subtracting 6 from both sides of the equation 3x + 6 = 19, resulting in 3x = 13.
