- System Of Equations

-----------------------------------

- Isolate x for x + x + 10 = 10: x = 0
For y = 10
Substitute x = 0
Y = 0 + 10
0 + 10 = 10
y = 10
X = 0
Y = 10

:

Answer:
h(x-5)=2x-5
Step-by-step explanation:
What we want to do is replacing x-5 with x and we got h(x-5)=2(x-5)+5, using the distributive property and simplify to the simplest expression is going to be h(x-5)=2x-5
