Chapter 3: Q42. (page 133)

Use a calculator to solve the equation. Check your solution.
$- 130.5 - 9 b = - 55.104 + 3.2 b$

Short Answer

Expert verified

The solution for the equation is $b = - 6.18$

Step by step solution

Step-1 – Given

The given equation is $0.75 m + 14 = 1.87 m - 10.3936$ .

Step-2 – To determine

We have to solve the equation using a calculator

Step-3 – Calculation

We first make one side equal to 0.

\begin{array}{l} - 130.5 - 9 b = - 55.104 + 3.2 b \\ - 130.5 - 9 b + 55.104 = - 55.104 + 3.2 b + 55.104 [Add55.104fromeachsides] \\ - 75.396 - 9 b = 3.2 b [Simplify] \\ - 75.396 - 9 b - 3.2 b = 3.2 b - 3.2 b [Subtract 3.2 b fromeachsides] \\ - 75.396 - 12.2 b = 0 [Simplify] \end{array}

Then we add 75.396 to both sides

So, we get: $- 12.2 b = 75.396$

Then divide both sides by $- 12.2$

$\begin{array}{l} \frac{- 12.2 b}{- 12.2} = \frac{75.396}{- 12.2} \\ b = - 6.18 \end{array}$

So the solution of the equation is $b = - 6.18$
