Question

1) Resolva as equações de 1° grau. (1.2 pontos)
a) 4x - 9 = 1-X
b) x + 5 = 20 - AX
c) 8x - 1 = 15 + 4x
d) 3.(2x - 5) = 9-22​

Answer 1

Explicação passo-a-passo:

a) 4x-9=1-x -> 4x+x=1+9 -> 5x=10 -> x=10/5 -> x=2

c) 8x-1=15+4x -> 8x-4x=15+1 -> 4x=16 -> x=16/4 -> x=4

d) 6x-15=9-22 -> 6x=2 -> x=2/6 -> x=0,33
