Question

X=3.6,y=?
6x+3y+6 is equal to 0 or not

Answer 1

Substituting the value of x

6(3.6.)+3y+6= 0

21.6+6= -3y

27.6= -3y

27.6/-3= y

y= 9.2

HOPE IT HELPS! ^_^

Answer 2

Equation to satisfy condition equal to zero or not

let first suppose equal to zero

6x+3y+6=0

6×3.6+3y+6=0

27.6+3y=0

y=-9.2

so for equal equal to zero value of y is -9.2 and equation not equal to zero satisfies any value  other than -9.2
