Chapter 2: Q 2.10 (page 102)

Solve: $12 [1 - 5 (4 z - 1)] = 3 (24 + 11 z)$ .

Short Answer

Expert verified

The solution is $z = 0$ .

Step by step solution

Step 1. Given information.

Solve the below linear equation,

$12 [1 - 5 (4 z - 1)] = 3 (24 + 11 z)$ .

Step 2. Use the Distributive Property to remove any parentheses.

Combine like terms and simplify.

$12 [1 - 5 (4 z - 1)] = 3 (24 + 11 z) 12 [1 - 20 z + 5] = 72 + 33 z 12 - 240 z + 60 = 72 + 33 z 72 - 240 z = 72 + 33 z 72 - 240 z - 72 = 72 + 33 z - 72 - 240 z = 33 z - 240 z - 33 z = 33 z - 33 z - 240 z = 0 z = 0$

Step 3. Check the solution.

Put $z = 0$ into the equation.

$12 [1 - 5 (4 z - 1)] = 3 (24 + 11 z) 12 [1 - 5 (4 \cdot 0 - 1)] = 3 (24 + 11 \cdot 0) 12 [1 + 5] = 3 (24) 12 \cdot 6 = 72 72 = 72$

Hence, the solution is correct.

Step 4. Conclusion.

The solution of the given linear equation is $z = 0$ .
