Question

suppose that f(x)=-x-7 and g(x)= x-12
solve for f(x)=0
solve for g(x)=0
solve for f(x)=g(x)

Answer 1

i know f(x)0=-7
g(x)0=-12
i just dont know the third one

Answer 2

f(x)=-x-7
g(x)= x-12
solve for f(x)=g(x)

-x-7=x-12

rearrange and solve. good luck

Answer 3

not sure still

Answer 4

-x-7=x-12

add x to both sides

-7 = 2x-12

add 12 to both sides

5 = 2x
