Answer:
One pair of equivalent expressions is:
x - 3y + 12
12 - 3y - 2x + x + 2x
Second,
x + 3y + 12
3x + 2y - 2x + y + 12
third,
3y + 12
x + 3y + 2x - 3x + 7 + 5
four,
3x + y - 12
4y + 3y + 3x - 6y - 10 - 2
Step-by-step explanation:
In order to match the equivalent expressions we have to put each expression in its simplest form
So,
One pair of equivalent expressions is:
x - 3y + 12
12 - 3y - 2x + x + 2x
Second,
x + 3y + 12
3x + 2y - 2x + y + 12
third,
3y + 12
x + 3y + 2x - 3x + 7 + 5
four,
3x + y - 12
4y + 3y + 3x - 6y - 10 - 2

The tangent ratio is an illustration of the trigonometry identity
The value of x that is not a solution of tan(x) = 1 is 3/4
The trigonometry identity is given as:
tan(x) = 1
Next, we test the x values using a calculator.
When , we have:
tan(-7/4) = 1
When x = 3/4, we have:
tan(3/4) = -1
When x = 5/4, we have:
tan(5/4) = 1
When x = /4, we have:
tan(/4) = 1
Hence, the value of x that is not a solution of tan(x) = 1 is 3/4
