Answer:
x = 4(y + 11).
Step-by-step 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.
