Answer:

Its Option C.

Step-by-step explanation:

-4x + 7 = 2y - 3

Substitute the given values in the given equation:-

(2,1):- -4(2) + 7 = -1 and 2(1) - 3 = -1 so (2,1) is a solution.

(5, -5):- -4(5) + 7 = -13 and 2(-5) - 3 = -13 so (5, -5) is also a solution.

To solve this, you divide 116 by four, this gets you 29. The loser got 29 votes. Then you subtract 116-29 which gives you 87. That is how many votes the winner received. Hope this helps

3p - 2(p-4) = 7p + 6

Serggg [28]

For this case we must find the value of the variable "p" of the following equation:

$3p-2 (p-4) = 7p + 6$

We apply distributive property on the left side of the equation taking into account that $+*-=-$ and $- * - = +$ :

$3p-2p + 8 = 7p + 6$

We add similar terms:

$p + 8 = 7p + 6$

We subtract $7p$ from both sides of the equation:

$p-7p + 8 = 6\\-6p + 8 = 6$

We subtract 8 from both sides of the equation:

$-6p = 6-8\\-6p = -2$

We divide by -6 on both sides of the equation:

$p = \frac {-2} {- 6}\\p = \frac {1} {3}$

Answer:

$p = \frac {1} {3}$
