Answer 1

Respuesta:

1. x = 14/17

2. x = - 2/5

3. x = - 20/7

4. x = 35/36

Explicación paso a paso:

1.

$2(x+7)=19x\\2x+14=19x\\2x-19x=-14\\-17x=-14\\x=\frac{14}{17}$

2.

$(x-4)=11x\\x-4=11x\\x-11x=4\\-10x=4\\x=-\frac{4}{10}=x=-\frac{2}{5}$

3.

$5(x-4)=12x\\5x-20=12x\\5x-12x=20\\-7x=20\\x=-\frac{20}{7}$

4.

$10(x+7)=82x\\10x+70=82x\\10x-82x=-70\\-72x=-70\\x=\frac{70}{72}=x=\frac{35}{36}$
