a) f(x)=2x-4
b) g(x)=3x+6
c) f(x) = 2x-3
d) y = -x + 3
e) f(x) = -3x + 5
f) y = x + 2
g)y=×+3
h) (24) = 3x+ 1
i) {(x) = -2x+ 1
j)y=10 - 2x​

Answer 1

Explicação passo-a-passo:

a) x=2

0=2x-4

2x=4

x=4/2

x=2

b) x=-2

3x+6=0

3x=-6

x=-6/3

x=-2

c) x=3/2

2x-3=0

2x=3

x=3/2

d) x=3

-x+3=0

-x=-3/(-1)

x=3

e) x=5/3

-3x+5=0

-3x=-5

x=-5/-3

x=5/3

f) x=-2

0=x+2

x+2=0

x=-2

g) x=-3

x+3=0

x=-3

h) x=-1/3

3x+1=0

3x=-1

x=-1/3

i)x=1/2

-2x+1=0

-2x=-1

x=-1/-2

x=1/2

j) x=5

10-2x=0

-2x=-10

x=-10/-2

x=5
