Question

2x = 5y +4 and 3x - 2y + 16 = 0 . find x and y

Answer 1

hope it will help you

Answer 2

first choose an equation.
2x = 5y + 4
x= 5y +4/2
then put the value of x in another equation.
3x-2y +16= 0
3(5y +4 /2)-2y +16=0
15y +12/2 - 2y +16=0
11y+12-4y/2 +16=0
11y+12/2 +16=0
11y+12/2=-16
11y+12=-16*2
11y+12=-32
11y=-33-12
11y=-44
y=-44/11
y=-4
then putting the value of y in the equation x=5y+4/2
x=5*-4+4/2
x=-16/2
x=-8
so ,x=-8and y =-4
