The midpoint of (3 x, -2) and (-4, 5y) is (1,4). find x, -y​
Mariana [72]

Answer:

(x,-y): (2,-2)

Step-by-step explanation:

M=(x+x)/2,(y+y)/2

Given (1,4)=

\frac{3x - 4}{2}

This implies:

1 =  \frac{3x - 4}{2}

3x - 4 = 2 \\ 3x = 2 + 4 \\  \frac{3x }{3}  =  \frac{6}{3}  \\ x = 2

In a similar way,

4 =  \frac{ - 2 + 5y}{2}  \\  - 2 + 5y = 8 \\ 5y = 10 \\ y = 2

The question demanded (x,-y)

Hence(2,-2) is the answer
