Question

find the value of x and y​

Answer 1

Step-by-step explanation:

4 x minus 3 y is equal to 20 second equation X 3 which gives 9 y - 3 x is equal to 270

now subtract the equation which gives

4x-3y=120

9x-3y=270

-5x = -150

x is 30

so y is 120-3y is 120

so y is equal to 240/3

y is 80
