Question

Solve the equation for the variable specified: 7ab + 5c = 4d for 'a'.

Answer 1

To solve the equation for 'a', subtract 5c from both sides and divide by 7b.

Step-by-step explanation:

To solve the equation for 'a', we need to isolate 'a' on one side of the equation. Here's the step-by-step process:

1. Subtract 5c from both sides of the equation: 7ab = 4d - 5c
2. Divide both sides of the equation by 7b: a = (4d - 5c) / (7b)

So the solution for 'a' in the equation 7ab + 5c = 4d is a = (4d - 5c) / (7b).
