Answer:
31/6
Step-by-step explanation:
Write all numbers above the common denominator so 6-5/6
Multiply 6 by 6
Then we have 36 -5 / 6
Subtract the numbers so 36 -5 = 31 and 6 stays the same
We end up with 31/6 or 5 1/6 or 5.16 as Alternative form
Answer:
x = {-1/5, 1}
Step-by-step explanation:
(5x - 2)² - 1 = 8
Add 1 to both sides
(5x - 2)² = 9
Take the square root of both sides
5x - 2 = ±3
------------------------------
<u>Solution I</u> for 5x - 2 = +3
5x - 2 = 3
add 2 to both sides
5x = 5
Divide both sides by 5
x = 1
------------------------------
<u>Solution II</u> for 5x - 2 = -3
5x - 2 = -3
add 2 to both sides
5x = -1
Divide both sides by 5
x = -1/5
-------------------------------
x = {-1/5, 1}
