Resposta:
X = 5
Explicação passo a passo:
2 (9x − 4) − 7 + (6 − 5x) 3 = 18
18x − 8 − 7 + (6 − 5x) × 3 = 18
18x − 15 + (6 − 5x) × 3 = 18
18x − 15 + 18 − 15x = 18
18x + 3 − 15x = 18
3x + 3 = 18
3x = 18 − 3
3x = 15
X = 15/3
2(9x-4)-7+(6-5x).3=18
18x-8-7+30-15x = 18
18x-15x = 18+8+7-30
3x = 3
x = 3/3
x = 1
