Question

15x - 5 + 2x = 10 ( x + 1 ) + 10x + 5 -8x

Answer 1

Resposta:

x=4

Explicação passo-a-passo:

15x - 5 + 2x = 10x + 10 + 10x + 5 -8x

15x + 2x - 10x - 10x + 8x = 10 + 5 + 5

5x = 20

x = 20/5

x=4

Answer 2

Resposta:

x=4

Explicação passo-a-passo:

15x - 5 + 2x = 10.( x + 1 ) + 10x + 5 -8x

15x+2x-5=10x+10+10x+5-8x

17x-5= 20x+10+5-8x

17x-5=12x+10+5

17x-5=12x+15

17x-12x=15+5

5x=20

x=20/5

x=4
