Question

Solve for X

y = 0.25x + -11

Please explain and provide evidence

Answer 1

x = 4(y + 11).

Explanation:

y = 0.25x + -11 Add 11 to both sides:

y + 11 = 0.25x + - 11 + 11

y + 11 = 0.25x Now multiply both sides by 40 to give x on its own:

4(y + 11) = 0.25x * 4

x = 4(y + 11).

Let's check if the answer is right by substituting 2 for x in:

y = 0.25x - 11

= 0.5 - 11 = -10.5.

Now substitute -10.5 for y and 2 for x in x = 4(y + 11):

2 = 4(-10.5 + 11) = 4 * 0.5 = 2.

So our answer is correct.

Answer 2

Unfortunately it can't be solved.

Explanation:

x is the all real number. which means it will have many solutions.
