Answer 1

Answer:

1.) $x=\frac{5}{12}$

2.) $=28986$

Step-by-step explanation:

1.) $\mathrm{Multiply\:the\:numbers:}\:7\cdot \:2=14$, $14x-2x-5=0.$

$\mathrm{Add\:similar\:elements:}\:14x-2x=12x$$, 12x-5=0.$

$\mathrm{Add\:}5\mathrm{\:to\:both\:sides}, 12x-5+5=0+5.\\12x=5, \mathrm{Divide\:both\:sides\:by\:}12.\\\frac{12x}{12}=\frac{5}{12}, x=\frac{5}{12}$

2.) $2+4-4\left(7\right)\left(-5\right)\cdot \:207=28986$

$=28986$

3.) ?, I can't read that. Please put it more 'configurative'.
