Answer:
x = 4
Step-by-step explanation:
(5x2 - 2x + 1) = (x - 1)
Simplify by multiplying 5 and 2.
(10 - 2x + 1) = (x - 1)
Combine like terms. Remove parentheses.
11 - 2x = x - 1
Cancel out - 2x to get the variable on one side.
- 2x + 2x = 0 x + 2x = 3x
11 = 3x - 1
Do the same with the 1.
12 = 3x
Divide.
x = 4
Answer:
x = 27.5
Step-by-step explanation:
You have to add 10.6 on the left to isolate 'x', and in turn you have to do the same to the right side.
Add 10.6 and 16.9
10.6+16.9 = 27.5
:)
(-10= xy + z ) (-z)
(-10-z = xy ) (1/y)
-10/y - z/y = x
x = -(10+z)/y
Convert 5 4/5 to a decimal. After doing so, you will find that the answer is C.
5.8 = 5.8
