The system of equations:
2 y = - x - 1
2 y = x + 5
---------------------
- x - 1 = x + 5
- 2 x = 5 + 1
- 2 x = 6
x = - 6 : 2
x = - 3
2 y = - 3 + 5
2 y = 2
y = 1
The solution is ( - 3 , 1 ).
Answer: The x-coordinate of the solution to the system is:  x = - 3.

IrinaK [193]

Answer:

5 boys

Step-by-step explanation:

boys to girls in math class = 3/12

3/12 can be reduced to 1/4

In the science class, the ratio is the same but there is a total of 20 girls.

Multiply the fraction 1/4 by 2/2, 3/3, 4/4, 5/5, etc. until you get x/20. Then you have 20 girls. x is the number of boys.

1/4 = 2/8 = 3/12 = 4/16 = 5/20

In science the ratio of 1/4 is the same as 5/20, so there are 5 boys.

Answer: 5 boys

What is the value of x?
rodikova [14]
1) expand the brackets 
6(-3 - x) - 2x = 14
-18 - 6x - 2x = 14
simplify
-18 - 8x = 14
then add 18 to both sides to get the x's on there own
-8x = 32
then divide by -8
x = 32/-8
x = -4

2) multiply everything by 7x
2 + (6 x 7x) + ( 17x × 7x) = 18 x 7x
2 + 42x + 119x^2 = 126x
put everything on one side
119x^2 - 84x + 2 = 0
then use quadratic equation to solve

x = 0.024671849 or 0.6812105039
