Question

Resolva as equaçães: v = (1,0)
A) 2z + 1 = 25 b) 2y + = y +20
C) 3x + 4 = y + 20 d) x + 15 =40
E) z - 3 = 12

Answer 1

Resposta:

A) 2z + 1 = 25

2z = 25 - 1

2z = 24

$z = \frac{24}{2}$

z = 12

B) 2y + 3 = y + 20

2y - y = 20 - 3

y = 17

C) 3x + 4 = 10

3x = 10 - 4

3x = 6

$x = \frac{6}{3}$

x = 2

D) x + 15 = 40

x = 40 - 15

x = 25

E) z - 3 = 12

z = 12 + 3

z = 15

F) y + 17 = 20

y = 20 - 17

y = 3
