Answer 2

To solve the equation (700:а+20)-50=100, follow these steps:

Step 1: Remove the parentheses using the distributive property. Step 2: Simplify the expression on the left side of the equation. Step 3: Solve for the variable а.

Given equation: (700/а + 20) - 50 = 100

Step 1: Remove the parentheses. 700/а + 20 - 50 = 100

Step 2: Simplify the expression. 700/а - 30 = 100

Step 3: Get the term with а on one side of the equation. 700/а = 100 + 30 700/а = 130

Step 4: Isolate а by getting rid of the fraction. To do this, we can cross-multiply. 700 = 130а

Step 5: Solve for а. а = 700/130 а = 5.38 (rounded to two decimal places)

The value of а that satisfies the equation is approximately 5.38.
