Answer:
I do not know if that x is a multiply sign or a variable so I'm going to answer both
If the x is a multiplication sign then the answer is -20 = -9
If the x is a variable then the answer is x = -2
Step-by-step explanation:
1/2(5 * -8) = -9
(1 * 5 * -8)/2 = -9
(5 * -8)/2 = -9
-40/2 = -9
-20 = -9
-20 ≠ -9
1/2(5x - 8) = -9
1(5x -8)/2 = -9
(5x - 8)/2 = -9
2((5x - 8)/2) = -9 * 2
2(5x - 8)/2 = -9 * 2
5x - 8 = -9 * 2
5x - 8 = -18
+8 +8
------------------
5x = -10
x = -10/5
x = -2
In this problem, we are asked to declare statements that describe the orders given as stated. In the first command, we are to define the element number of the element specified, which by, in this case, is oxygen. This is expressed: Element number = 8. Then we name the element that is element = oxygen. The third command specifies the atomic weight of the elementoxygen = 15.9994. For the last command, the expression is atomic weight = oxygen. It is important to arrange the commands in order so that the program that understands the data executes the orders well and translate them into output.

Step-by-step explanation:
hello :
(2x + 9)(3-z) = 0 means : 2x+9=0 or 3-z=0
x= -9/2 or z=3
