7(x-2)=28 Can somebody help me and show the steps?
1 answer:
Since the 7 is in front of the parentheses you must multiply it by everything inside the parentheses. 7 times X is 7X and 7 times -2 is -14. Then you need to make the X be by itself on one side, to do that you have to add 14 to -14 to make it disappear, and also add 14 to the other side, to 28. Then you divide both sides by 7 to make X be by itself.
7(x-2)=28
7X-14=28
7x=42
X=6
7(x-2)=28
7X-14=28
7x=42
X=6

Answer:
8 + 3 + -6x
Step-by-step explanation:
First we need to find the like terms so that we could add them. In this case the like terms are,
1. 6x , -2x , -10x
So, these are the only terms that we can add in this expression.
Hence,
=> 8 + 3 + (6x - 2x - 10x)
=> 8 + 3 + -6x
And this is as simple as this expression can go until we find the value of "x" which is not yet told.
Hope my answer helped.
