Givivn h(x)=-x+1, solve for x when h(x)=0

Answers

Answer:

x = 1

Step-by-step explanation:

given h(x) = - x + 1

when h(x) = 0 , that is

- x + 1 = 0 ( subtract 1 from both sides )

- x + 1 - 1 = 0 - 1 ( simplify both sides )

- x = - 1 ( multiply both sides by - 1 )

- 1 × - x = - 1 × - 1 , that is

x = 1
