Answer:
1. y=7x+5
y=7x+5
Substitute y=0
0=7x+5
Move the variable to the left
-7x=5
Divide the both sides of the equation by -7
x=-5/7 or x=-0.71
2. h(x)=-4x+1
h(x)=-4x+1
Same process in the previous number
= 0=-4x+1
= 4x=1
= x=1/4 or x=0.25
3. y=6x-7
Same process in the previous number
= 0=6x-7
= -6x=-7
= x=7/6 or x=1 1/2 or x=1.16
4. g(x)=2x+4
Same process in the previous number
= 0=2x+4
= -2x=4
= x=-2
5. G(x)=3x-6
Same process in the previous number
= 0=3x-6
= -3x=-6
= x=2
