3-x\geq 0 x+5<0
For the quotient to be ≤0, one of the values 3-x and x+5 has to be ≥0, the other has to be ≤0, and x+5 cannot be zero. Consider the case when 3-x\geq 0 and x+5 is negative.
x<-5
Yr ateb sy'n bodloni'r ddau anghydraddoldeb yw x<-5.
3-x\leq 0 x+5>0
Consider the case when 3-x\leq 0 and x+5 is positive.
x\geq 3
Yr ateb sy'n bodloni'r ddau anghydraddoldeb yw x\geq 3.
x<-5\text{; }x\geq 3
Yr ateb terfynol yw undeb yr atebion a gafwyd.
