Question

7(y+3)=5y+8 Is this A.Solution B.No Solution C. Infinite Solution

Answer 1

First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:

$a(b + c) = ab + ac$

Using this, we can multiply the 7 out to the $y$ and 3. This gives us:

$7y + 21 = 5y + 8$

Now, let's solve for $y$:

$2y + 21 = 8$

$2y = -13$

$y = - \dfrac{13}{2}$

We can see that there is one solution for this equation because $y$ is equal to one definite value after solving. Thus, our answer is A, one solution.
