To solve for a variable, you need to get it (x) by itself.
x² - 14 + 31 = 63 Add 31 to -14
x² + 17 = 63 Subtract 17 from both sides of the equation
x² = 46 Square root both sides
x =
Check your work by plugging in
for x and then 
.
² - 14 + 31 = 63 Square
46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63
² - 14 + 31 = 63 Square
46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63
So, x is and .

Answer:
y = 1
Step-by-step explanation:
600,000 ÷ 1/2 = 300,000
c = 600,000
y = 1/2
x = 300,000
