1 Simplifying

5a + 4b + -3a = 0

Reorder the terms:

5a + -3a + 4b = 0

Combine like terms: 5a + -3a = 2a

2a + 4b = 0

Solving

2a + 4b = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-4b' to each side of the equation.

2a + 4b + -4b = 0 + -4b

Combine like terms: 4b + -4b = 0

2a + 0 = 0 + -4b

2a = 0 + -4b

Remove the zero:

2a = -4b

Divide each side by '2'.

a = -2b

Simplifying

a = -2b

Which diagram most effectively show how a voter influenced policy? Answer C
bagirrra123 [75]

The correct option is C

Political parties are fundamental pieces for political plurality. In modern democracies, parties have become the gears of political conflict, generate it, contain it and, as the case may be, solve it. The opportunities for electoral participation have been framed by the decision of the parties and, to this extent, questions such as political culture depend on the perception of the citizenship on the partisan environment. We also see that after choosing representatives of the people, a very important tool that people have is to write to them or show their inclinations to certain projects by different trucks, such as a letter, a note in a newspaper or magazine or through internet pages.
