The properties used, in order, are:
- Distributive.
- Addition or subtraction property of equality.
- Addition or subtraction property of equality.
- multiplicationn or division property of equality.
What is used in each step of the demonstration?
We start by writing the linear equation:
3*(x + 2) = 4x + 1
The first step is using the distributive property to distribute the left product.
3x + 6 = 4x + 1
Then we use the addition property of equality to subtract 4x in both sides, we will get:
-x + 6 = 1
And we use it again to subtract 6 in both sides:
-x = 1 - 6 = -5
Finally, we multiply both sides by -1 (multiplication property of the equality)
x = 5
That is the solution of the linear equation.
