Astudent solves the following equation and
determines that the solution is -2. is the
student correct? explain.
3
a + 2
6
a? - 4
1
a - 2

The solution of the equation is (a = -2) and this can be determined by using the arithmetic operations.

Given :

Equation  -  

The following steps can be used to evaluate the given equation:

Step 1 - Write the equation.

Step 2 - Rewrite the above equation.

Step 3 - Take the LCM.

Step 4 - Further simplify the above expression.

Step 5 - Cancel out the denominator of both sides and then further simplify.

2a - 8 = 6a

a = -2

No, the student is not correct

Step-by-step explanation:

Assuming the equation is  

We can see that  will render the equation undefined.

This is because there will be a division by zero error

Therefore cannot be a solution.

It is an extraneous solution solution.

Hence the student is incorrect

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
