65-4=8(2+1/4d)
We move all terms to the left:
65-4-(8(2+1/4d))=0
Domain of the equation: 4d))!=0We add all the numbers together, and all the variables
d!=0/1
d!=0
d∈R
-(8(1/4d+2))+65-4=0
We add all the numbers together, and all the variables
-(8(1/4d+2))+61=0
We multiply all the terms by the denominator
-(8(1+61*4d+2))=0
We calculate terms in parentheses: -(8(1+61*4d+2)), so:We get rid of parentheses
8(1+61*4d+2)
We add all the numbers together, and all the variables
8(61*4d+3)
We multiply parentheses
1952d+24
Back to the equation:
-(1952d+24)
-1952d-24=0
We move all terms containing d to the left, all other terms to the right
-1952d=24
d=24/-1952
d=-3/244
