Y=2x-4 
X+2y=10 
Put y into the x equation 
X+2(2x-4) =10 
Expand and simplify 
X+4x-8=10 
5x-8 =10 
5x=10+8 
5x=18 
X=18/5 
Insert x into the original equation to get y 
Y=2x-4 
Y=2(18/5)-4 
Y=16/5
        
             
        
        
        
You would first turn it into an improper fraction, to do this you leave the denominator(bottom number) then times it by your variable and add the numerator(top number)
Ex:
1 3/4x1/3= 7/12

Answer:
x=b/(ay)
Step-by-step explanation:
To make x the subject of the formula, we basically have to isolate the x.
To do this we first multiply both sides by x.
xy=b/a
Now, to isolate the x, we simply divide by y,
x=b/(ay)
So x=b/(ay) is our answer
