Answer:
x = 7
Step-by-step explanation:
In an isosceles triangle, both legs are always congruent. The length of one leg is given, and the other leg has to be the same. The perimeter of this triangle can be written as:

With this equation, all you need to do is solve for x.

No, because if you plug in 10 for y and 5 for x then solve the inequality says 10>10
U would replace x with 0 in the equation and solve and then do the same but with y and those are ur x and y values of ur point
Ex: 2x+5y=15
2(0) +5y=15
5y=15
Y=3
2x+5(0)=15
2x=15
X=7.5
So ur point would be (7.5,3)
