Question

*Em cada item a seguir, determine a medida X em graus:
A) 6x+16°=8x
B) 7x-19°=6x+3°
C) 4x-1°=5x-14°
D) 3x+4°=7/5 x​

Answer 1

Resposta:

A) 6x +16 =8x

6x -8x = 16

- 2x =16

x = 16 ÷ -2

x = - 8

b) 7x - 19 = 6x +3

7x - 6x = +3 + 19

1 x = 22

x = 22

c ) 4x - 1 = 5x - 14

4x - 5x = -14 + 1

- 1 x = - 15

x = 15
