There are no parenthesis
There are no exponents
Now, we do multiplication and division from left to right
(9x9) + 8 - (8/10)
=
81 + 8 - 0.8
Now, we do addition and subtraction from left to right
(81 + 8) - 0.8
89 - 0.8
=
88.2
Subtract 24 from both sides.
z + 24 = 10
- 24 -24
z = -14

Step-by-step explanation:
Answer:
x = 0 and x= 3
Step-by-step explanation:
2x ² = x² + 3x
so
2x² - x² - 3x =0
x²- 3x = 0
x ( x - 3 ) = 0
x = 0
x = 3
