Question

how to solve this?
x-5y =8
x*2 +9y*2+3x =30 +xy​

Answer 1

Step-by-step explanation:

Its a simultaneous equation.

First solve for x in the first equation: x = 8+5y

then substitute all x in the second equation with (8+5y)

(8+5y)^2+9y^2+3(8+5y) = 30y(8+5y)

now it becomes a simple quadratic equation.
