Question

-7(5r + 2) = -14 - r

Explanation:

Step1: Apply distributive property

$-7(5r + 2) = -7\times5r + (-7)\times2$

Step2: Calculate each term

$-35r - 14 = -14 - r$

Step3: Isolate variable terms

$-35r + r = -14 + 14$

Step4: Simplify both sides

$-34r = 0$

Step5: Solve for r

$r = \frac{0}{-34}$

Answer:

$r = 0$
