How can the following equation be solved?
3x + 4y = 20
The given equation is a linear equation with two variables (x and y). To solve this equation, you need to isolate one variable in terms of the other variable.
3x + 4y = 20
x + (4/3)y = 20/3
x = (20 - 4y)/3
So, the solution set of the equation is {(x,y) | x = -(4/3)y + 20/3}.
Below is an instruction that describes a task. Write a response that appropriately completes the request.
