Resposta: 0 = 400
Explicação Passo a Passo:
7(2x - 50) -4x = 10(5 + x)
14x - 350 -4x = 10(5 + x)
14x - 350 -4x = 10(5 + x)
10x - 350 = 10(5 + x)
10x - 350 = 10(5 + x)
10x - 350 = 10(x + 5)
10x - 350 = 10(x + 5)
10x - 350 = 10x + 50
10x - 350 = 10x + 50
10x - 350 + 350 = 10x + 50 + 350
10x - 350 + 350 = 10x + 50 + 350
10x = 10x + 50 + 350
10x = 10x + 50 + 350
10x = 10x + 400
10x = 10x + 400
10x - 10x = 10x + 400 - 10x
10x - 10x = 10x + 400 - 10x
0 = 10x + 400 - 10x
0 = 10x + 400 - 10x
0 = 400
