At what value of x does the function y = 4x-1 take on a value of 11?

In order to determine at what values of the variable x the function given by the equation y = 4x – 1 takes a value equal to 11, you need to substitute 11 instead of y and solve the equations for the variable x.
So, substitute 11 for y and get the equation:
11 = 4x – 1;
We transfer terms with a variable to the left side of the equation, and not containing a variable to the right side. When transferring terms from one side of the equation to another, do not forget to reverse the signs.
– 4x = – 1 – 11;
– 4x = – 12;
x = – 12 / – 4;
x = 3.
Answer: for x = 3, the function takes on a value equal to 11.
