Question

B)3×+4×-6=8
C)7×=10-2+5×

Answer 1

B) 3x + 4x - 6 = 8

7x = 8 + 6

7x = 14

x= 14/7

x= 2

C) 7x = 10 - 2 + 5x

7x - 5x = 8

2x = 8

x= 8/2

x= 4

Answer 2

Explicação:

B)

3x + 4x - 6 = 8

7x = 8 + 6

7x = 14

x = 14 ÷ 7

x = 2

C)

7x = 10 - 2 + 5x

7x - 5x = 8

2x = 8

x = 8 ÷ 2

x = 4
