(63x+(100-x)65)/100=64.9278
We move all terms to the left:
(63x+(100-x)65)/100-(64.9278)=0
We add all the numbers together, and all the variables
(63x+(-1x+100)65)/100-(64.9278)=0
We add all the numbers together, and all the variables
(63x+(-1x+100)65)/100-64.9278=0
We multiply all the terms by the denominator
(63x+(-1x+100)65)-(64.9278)*100=0
We calculate terms in parentheses: +(63x+(-1x+100)65), so:We add all the numbers together, and all the variables
63x+(-1x+100)65
We multiply parentheses
63x-65x+6500
We add all the numbers together, and all the variables
-2x+6500
Back to the equation:
+(-2x+6500)
(-2x+6500)-6492.78=0
We get rid of parentheses
-2x+6500-6492.78=0
We add all the numbers together, and all the variables
-2x+7.2200000000003=0
We move all terms containing x to the left, all other terms to the right
-2x=-7.2200000000003
x=-7.2200000000003/-2
x=3+1/1.6393442622947
