Question

Resolva as equações.


(a) x − 17 = −9


(b) −2x = 10


(c) 3x + 2 = 2x − 11


(d) 2x + 14 = 5x − 1


(e) 5x + 4 − 2x = 26 − 3x


(f) + 1 = x + 3
2


(g) 3 ∙ ( x − 2) − (1 − x ) = 13


(h) x − ( x + 1) = 12 − (3 x − 2)

Answer 1

Explicação passo-a-passo:

a) X = -9 + 17

X = 8

b) X = 10 ÷ 2

X = 5

c) 3X - 2X = -11 - 2

X = - 13

d) 2X - 5X = -1 -14

-3X = -15

X= 15÷3

X = 5

e) 5X - 2X + 3X = 26 - 4

6X = 22

X = 22÷6

X= 3,6666667

f) tá faltando informação

g) 3X - 6 - 1 + X = 13

4X = 13 + 7

4X = 20

X = 5

h) X + X - 1 = 12 - 3X + 2

2X + 3X = 12 + 2 + 1

5X = 15

X = 15÷5

X= 3
