Use the order of operations to simplify the following algebraic expression.
@rational help me please????
Okay, so you know the order of operations, correct?
yes!
PEMDAS
Okay, well what this needs first is to combine like terms. So combine the ones that are being multiplied by x (6x, -15x, and 4x)
If you use PEMDAS it will be really easy to get the answer
I THINK combining the like terms is first...let me check if I'm correct
what is the value of X?
X is a number you don't know. It's literally a number. But you don't know the value.
so how do we find it, thats the only trouble I'm having.
Okay, I'm sorry. Don't combine the like term first. Use PEMDAS. So theres no grouping symbols, or exponents. So the next thing to do is division (-15x / 3, which equals -5x) Do you see what I did there? \[6x-15x \div3+4x \times 2\]\[6x-5x+4x \times 2\]
What do you think is next?
1x+8x=?
9x!!!
i see...u don't need to know x!!
1x+8x = 9x Also remember 1x = x (because one times a number is that number. :))
Yes, you don't need to know x for equations like this. :) Great job. :D
