Question

equação do 1° grau

f) 4X - 9 = 23

g) 7X - 33 = - 12

h) 33 + X = 5 -3X

i) 2X = 14

j) 7X = 14

w) 4X = - 12​

Answer 1

Explicação passo-a-passo:

f) 4X - 9 = 23

4X = 23 + 9

4X = 32

X = 32/4

X = 8

g) 7X - 33 = - 12

7X = - 12 +33

7X = 21

X = 21/7

X = 3

h) 33 + X = 5 -3X

X + 3X = 5 - 33

4X = - 28

X = - 28/4

X = - 7

i) 2X = 14

2X = 14

X = 14/2

X = 7

j) 7X = 14

X = 14/7

X = 2

w) 4X = - 12

X = - 12/4

X = - 3

Answer 2

Explicação passo-a-passo:

f)4X - 9 = 23

4X=23+9

4X=32

X=32/4=8

g)7X - 33 = - 12

7X=-12+33

7X=21

X=21/7=3

h) 33 + X = 5 -3X

X+3X=5-33

4X=-28

X=28:4=-7

i)2X = 14

X=14/2=7

j) 7X = 14

X=14/7=2

w) 4X = - 12

X=12:4

X=-3
