Chapter 2: Q.22. (page 111)

Solve the linear equation $- 12 + 8 (x - 5) = - 4 + 3 (5 x - 2)$ .

Short Answer

Expert verified

The solution is $x = - 6$ .

Step by step solution

Step 1. Given information.

The given equation is $- 12 + 8 (x - 5) = - 4 + 3 (5 x - 2)$ .

Step 2. Apply the distributive property to simplify the equation.

Simplify each side of the equation.

$- 12 + 8 x - 8 \times 5 = - 4 + 3 \times 5 x - 3 \times 2 - 12 + 8 x - 40 = - 4 + 15 x - 6 8 x - 52 = 15 x - 10$

Step 3. Collect all variables terms on other side of the equation.

Subtract $15 x$ from each side.

$8 x - 52 - 15 x = 15 x - 10 - 15 x - 7 x - 52 = - 10$

Step 4. Collect all constant terms on other side of the equation and then simplify.

Add $52$ to each side.

$- 7 x - 52 + 52 = - 10 + 52 - 7 x = 42$

Divide each side by $- 7$ .

$\frac{- 7 x}{- 7} = \frac{42}{- 7} x = - 6$

Hence, the solution of the given linear equation is $x = - 6$ .
