Answer:
(½x+½y)²=6
Step-by-step explanation:
x^2 + y^2 = 14, xy=5
(A+B)^2=A^2 +2AB+B^2... (*)
(1/2x+1/2y)^2 =(*)
(1/2x)^2 +2(1/2x)(1/2y)+(1/2y)^2 =
1/4x^2 +1/2xy+1/4y^2=
1/4(x^2 +y^2) +1/2(xy)=
1/4*14+1/2*5=
14/4+5/2=
14/4+10/4=
24/4=6

Answer:
x=2 and y=3.
Step-by-step explanation:
Let the one number be x and the other number be y.
ATQ, 2x=1+y and x+y=5. x=2 and y=3.
 
        
             
        
        
        
To solve this, you need to isolate/get the variable "m" by itself in the equation:
1. 2m - 1 = 3m    Subtract 2m on both sides to get "m" on one side of the equation
2m - 2m - 1 = 3m - 2m
-1 = m
2. 2m = 1 + m     Subtract m on both sides to get "m" on one side of the equation
2m - m = 1 + m - m
m = 1
3. m - 1 = 2       Add 1 on both sides to get "m" by itself
m - 1 + 1 = 2 + 1
m = 3
4. 2 + m = 3    Subtract 2 on both sides to get "m" by itself
m = 1
5. -2 + m = 1      Add 2 on both sides to get "m" by itself
m = 3
6. 3 = 1 + m     Subtract 1 on both sides to get "m" by itself
2 = m
