Answer:
Distributive Property
Step-by-step explanation:
3(x-4)=2x+7
Using Distributive property on left hand side we get
3*x-3*4 = 2x+7
3x-12=2x+7
Now we bring all the terms to one side of the equation, make sure we change sign while moving them to other side of =
3x-12-2x-7=0
Now bring the terms with x together and constant terms also
3x-2x -12-7=0
Simplifying the above polynomial
x-19=0
Now we add 19 on both sides
x-19+19=0+19
x-0=19
Hence x=19
