5x(8 - 4)/4 - 2
Remember to follow PEMDAS.
First, subtract 8 and 4
8 - 4 = 4
5x(4)/4 - 2
Next, follow the left -> right rule, and multiply 5x and 4
5x(4) = 20x
Divide by 4
20x/4 = 5x
Finally, note that one has a variable, and the other has a constant, and so you cannot combine.
5x - 2 is your answer
hope this helps
Answer:
24u + 10
Step-by-step explanation:
first rearrange the terms
4(10+6u)
4(6u+10)
then distribute the 4
4(6u) = 24u
4(10) = 10
then you get 24u + 10
Answer:
you just need to devide by 2 the second equation
Step-by-step explanation:
- -x + y = 2 (you leave it as it is)
- 2x + 4y =32 => 2x/2 +4y/2 = 32/2
=> x + 2y =16
we can devide or multiply in an equation by any number we want, as long as we do it to every term.
You were right, its the second choice CA=CB+BA
