The answer:
_____________________________________________
x = (⅔)y ;
y = 3x/2.
_____________________________________________
Given:
x + (⅓)y + x - (2/4)<span>y - x = (3/6)y ;
______________________________________
</span>
Take the: x + x - x = 1x + 1x - 1x = 2x - 1x = 1x = x ;
and rewrite:
x + (⅓)y - (2/4)y = (3/6)y ;
_______________________________
Note that: (2/4)y = (<span>½)y ;
and: (3/6)y = (</span><span>½)y ; so;
___________________________
Rewrite as:
____________________________
</span>x + (⅓)y - (½)y = (½)y ;
Add "(½)y" to EACH SIDE of the equation;
_________________________________
x + (⅓)y - (½)y + (½)y = (½)y + (½)y ;
to get: x + (⅓)y = y ;
x = 1y - (⅓)y = (3/3) y - (1/3)y - [ (3-1)/3] y = (⅔)y ;
So: x = (<span>⅔)y ;
In terms of "y" ;
Given: </span>(⅔)y = x ; Multiply each side of the equation by "3" ;
3*[(⅔)y] = 3*x ;
to get: 2y = 3x ;
Now, divide EACH SIDE of the equation by "2" ; to isolate "y" on one side of the equation; and to solve for "y" (in terms of "x"):
2y / 2 = 3x / 2 ;
to get:
y = 3x/2 ;

15.9 / 100 = c / 25,250....15.9 c sections to 100 women = c to 25,250 women
cross multiply
(100)(c) = (15.9)(25,250)
100c = 401475
c = 401475/100
c = 4014.75 <===
Answer:
5x -2y = -10
Step-by-step explanation:
Slope-intercept form of the equation for a line is ...
y = mx + b . . . . where m is the slope and b is the y-intercept.
Using the given numbers, the equation is ...
y = 5/2x + 5
Multiplying by 2 gives ...
2y = 5x + 10
Subtracting 2y+10 puts the equation into standard form, with positive leading coefficient and mutually prime coefficients.
5x - 2y = -10
Plug in x = 12 and y = -5 into the given equation:-
3(12) - 3(-5) = 36 + 15 = 51 Not 21
So (12,-5) is not a solution.
