Step-by-step explanation:
The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write
or

Also, note that the angle (4x - 7) and
are vertical angles, which means that they are equal to each other. Therefore,

Answer: There is one solution to the given equation.
Step-by-step explanation: We are given to find the number of solutions to the following equation :

Since the given equation is linear in one variable x, so it will have only one solution.
The solution of equation (i) is given by

Thus, there is one solution to the given equation.
Answer:
mathematics is inclusive, so A or B is a set of things where each of them must be ... Kevin Houston in his book[2] gives an idea to think of a proof
Step-by-step explanation:
The answer is A because it is the only equation that works for all the values on the table
