Question

aplicar propiedad distributiva y hallar el valor de x.. 1)2.(x+2)=11-3x+3 ... 2)3.(x.2)=27-2x+2 .. 3)7.(x+3)+4.(x.1)=72

Answer 1

1)
$2x + 4 = 11 - 3x + 3 \\ 2x + 3x = 11 + 3 - 4 \\ 5x = 10 \\ x = 10 \div 5 \\ x = 2$

2)
$6x = 27 - 2x + 2 \\ 6x + 2x = 27 + 2 \\ 8x = 29 \\ x = 29 \div 8$

3)
$7x + 21 + 4x = 72 \\ 7x + 4x = 72 - 21 \\ 11x = 51 \\ x = 51 \div 11$
