Just multiply 18 bye 4 at least I think that’s how u do it in my opinion plz don’t judge me
<span>We move all terms to the left:
-840-(-15(-7x+7))=0
</span>We calculate terms in parentheses: -(-15(-7x+7)), so:
-15(-7x+7)
We multiply parentheses
105x-105
Back to the equation:
<span>
-(105x-105)
</span>
<span>We get rid of parentheses
-105x+105-840=0
We add all the numbers together, and all the variables
-105x-735=0
We move all terms containing x to the left, all other terms to the right
-105x=735
x=735/-105
x=-7
</span>
<span>A </span>negative exponent<span> shows that the decimal point is shifted that number of places to the left. In </span>scientific notation<span>, the digit term indicates the number of significant figures in the number</span>
