Question

F) 9x+5=4x


H)4x-12=x


G)60+13x=3x

Answer 1

Resposta:

f) -1

h) 4

g) -6

Explicação passo-a-passo:

F) 9x +5 = 4x

9x - 4x = -5

5x = -5

x = -5 ÷ 5

x= -1

h) 4x -12 = x

4x -x = 12

3x = 12

x = 12 ÷ 3

x = 4

g) 60 + 13x = 3x

60 = 3x - 13x

60 = -10x

60 ÷ (-10) = x

-6= x

x= -6
