Chapter 12: Q41. (page 691)

Solve the equation. Check your solution.
$4 x + 7 = - 113$

Short Answer

Expert verified

The solution of equation is -30.

Step by step solution

Step 1. Given Information.

The given equation is $4 x + 7 = - 113$ .

Step 2. Calculation.

Solve the given equation by shifting the constant from left hand side to right hand side.

$\begin{matrix} 4 x + 7 = - 113 \\ 4 x = - 113 - 7 \\ 4 x = - 120 \end{matrix}$

Divide the equation by 4.

$\begin{matrix} \frac{4 x}{4} = \frac{- 120}{4} \\ x = - 30 \end{matrix}$

Hence, the value of x after solving the equation is -30.

Step 3. Check the answer

Substitute -30 for x in the given equation

$\begin{matrix} 4 (- 30) + 7 = - 113 \\ - 120 + 7 = - 113 \\ - 113 = - 113 \end{matrix}$

Since left side equal to the right side. Therefor the solution of the equation is -30.
