The correct answer is X=-2.

First remove the parentheses and factor out 2.

1/2•(2-6x)-4(x+3/2)=-(x-3)+4 turns into
1/2•2(1-3x)-4(x+3/2)=-(x-3)+4.
Then distribute -4 through the parentheses,
1/2•2(1-3x)-4x-6=-(x-3)+4
Then change the sign of the x-3 to x+3,
1/2•2(1-3x)-4x-6=-x+3+4

Then reduce the numbers with the greatest common factor which is 2,
and remove unnecessary parentheses,
1-3x-4x-6=-x+7
Then calculate the differences and collect like terms,
-5-7x=-x+7

Then move the variable to the left side and change its sign, and move the constant to the right hand side and change its sign,
-7x+x=7+5
Then add and collect the like terms,
-6x=12
And finally divide both sides by -6 to get X=-2.

Whew lol

Answer: x = -2

Step-by-step explanation:

<u>Given expression</u>

(1/2) (2 - 6x) - 4 (x + 3/2) = - (x - 3) + 4

<u>Expand parentheses and apply the distributive property when there is a constant outside of the parentheses</u>

(1/2) · 2 - (1/2) · 6x - 4 · x - 4 · (3/2) = - x + 3 + 4

1 - 3x - 4x - 6 = -x + 3 + 4

<u>Combine like terms</u>

(1 - 6) - (3x + 4x) = -x + (3 + 4)

-5 - 7x = -x + 7

<u>Add x on both sides</u>

-5 - 7x + x = -x + 7 + x

-5 - 6x = 7

<u>Add 5 on both sides</u>

-5 - 6x + 5 = 7 + 5

-6x = 12

<u>Divide -6 on both sides</u>

-6x / -6 = 12 / -6

\boxed{x=-2}

Hope this helps!! :)

o-na [289]

This question s incomplete, the complete question is;

The Watson family and the Thompson family each used their sprinklers last summer. The Watson family's sprinkler was used for 15 hours. The Thompson family's sprinkler was used for 30 hours.

There was a combined total output of 1050 of water. What was the water output rate for each sprinkler if the sum of the two rates was 55L per hour  

Answer:

The Watson family sprinkler is 40 L/hr while Thompson family sprinkler is 15 L/hr

Step-by-step explanation:

Given the data in the question;

let water p rate for Watson family and the Thompson family sprinklers be represented by x and y respectively

so

x + y = 55  ----------------equ1

x = 55 - y ------------------qu2

also

15x + 30y = 1050

x + 2y = 70 --------------equ3

input equ2 into equ3

(55 - y) + 2y = 70

- y + 2y = 70 - 55

y = 15

input value of y into equ1

x + 15 = 55

x = 55 - 15

x = 40

Therefore, The Watson family sprinkler is 40 L/hr while Thompson family sprinkler is 15 L/hr
