Answer 1

Resposta:

2(2x+7)+3(3x-5)=3(4x-5)-1

2(2x+7)+3(3x-5)=3(4x-5)-14x+14 + 9x-15= 12x-15-1

2(2x+7)+3(3x-5)=3(4x-5)-14x+14 + 9x-15= 12x-15-14x + 9x - 12x= -15-1-14+15

2(2x+7)+3(3x-5)=3(4x-5)-14x+14 + 9x-15= 12x-15-14x + 9x - 12x= -15-1-14+1513x - 12x= -30+15

2(2x+7)+3(3x-5)=3(4x-5)-14x+14 + 9x-15= 12x-15-14x + 9x - 12x= -15-1-14+1513x - 12x= -30+15x = -15
