Solve the system of equations is given below 2x+3y=18 x+7y=31
Veronika [31]
{2x + 3y = 18
x + 7y = 31}


2x+ 3y = 18
x=31-7

2(31-7)+3y=18

y=4

x=31-7*4
x=3

(x,y) = (3,4)

System of conics help
ZanzabumX [31]

Answer:

Solutions are (6,3) and (-2,3).

Step-by-step explanation:

From the first equation given we can write:

(x-2)^{2} = 16-(y-3)^{2}\\  

substituting for (x-2)^{2} in the second equation given we get

\frac{16-(y-3)^{2}}{16} + \frac{(y-3)^{2}}{64} = 1

\frac{-(y-3)^{2}}{16} + \frac{(y-3)^{2}}{64} =0

∴ y=3

Putting y=3 in the first equation we get

(x-2)^{2} = 16

x-2 = ±4

Hence x=6 or x=-2.
