Question

Solve the equation ( 3x/5 - 2 = 7 ) using the flowchart method.

a) ( x = 10 )
b) ( x = 15 )
c) ( x = 25 )
d) ( x = 35 )

Answer 1

To solve the equation (3x/5 - 2 = 7) using the flowchart method, add 2 to both sides, multiply both sides by 5, and divide both sides by 3 to solve for x. The correct answer is x = 15.

Step-by-step explanation:

To solve the equation (3x/5 - 2 = 7) using the flowchart method, we can follow the steps below:

1. Add 2 to both sides of the equation to isolate the variable: 3x/5 = 9
2. Multiply both sides of the equation by 5 to eliminate the fraction: 3x = 45
3. Divide both sides of the equation by 3 to solve for x: x = 15

Therefore, the correct answer is (b) x = 15.
