Question

Me ajudem por favor

Answer 1

Vou resolver a questão 10...

a) 6x = 2x + 16

6x - 2x = 16

4x = 16

x = 16 ÷ 4

x = 4

b) 2x - 5 = x+1

2x - x = 1 +5

x= 6

c) 2x+3 = x+4

2x -x = 4-3

x = 1

d) 5x +7 = 4x+10

5x - 4x = 10-7

x = 3

e) 4x-10= 2x +2

4x- 2x = 2 +10

2x = 12

x = 12 ÷ 2

x= 6

f) 4x - 7 = 8x-2

4x - 8x = -2 +7

- 4x = 5
