Chapter 3: Q. 6E (page 133)

Solve the equation. Check your solution.
$114 + 5 y = 50 - 4 y$

Short Answer

Expert verified

The solution for the equation $114 + 5 y = 50 - 4 y$ is $y = 4$ .

Step by step solution

– Separate the variable and constants

Write the original equation and separate the variable and constants.

$\begin{matrix} 114 + 5 y = 50 - 4 y \\ 14 + 5 y - 5 y = 50 - 4 y - 5 y [Substract5yfromeachside.] \\ 14 = 50 - 9 y [Simplify.] \\ 14 - 50 = 50 - 9 y - 50 [Subtract50fromeachside.] \\ - 36 = - 9 y [Simplify.] \end{matrix}$

– Solve for y

Now, divide both sides of the equation by 9.

$\begin{matrix} - \frac{36}{9} = - \frac{9 y}{9} \\ y = 4 \end{matrix}$

Therefore, the solution of the equation is $y = 4$ .

– Check the solution

To check the solution, write the original equation and substitute the value ofy.

$114 + 5 y = 50 - 4 y$

Now, substitute $y = 4$ and check the result.

$\begin{matrix} 14 + 5 (4) = 50 - 4 (4) \\ 14 + 20 = 50 - 16 \\ 34 = 34 \end{matrix}$

As the left-hand side is equal to right hand side, this signifies that the solution is correct.
