lol it looks complicated

1. first distribute the parentheses

6x+6+2x-14=x+3

2. now add like terms

8x-8=x+3

3. now substract the x on the right side of the equation with the x on the left side of the equation

7x-8=3

4. now add 8 to both side because you are trying to get x alone

7x=11

5. now divide each side of the equation by 7

x=11/7

6. the answer should be x=1.57 or 1.6 if u round up

first you have to get rid of your parenthesis. for the first part 3(2x+2) you take the 3 and times it by the 2x and the 2 which will equal 6x+6. for the second part you pretty much do the same thing. 2(x-7) take the 2 times the x and times the -7. which will come out to be 2x-14. so now you will end up having 6x+6+2x-14=x+3 from distributing the parenthesis. then you do like terms 8x - 8 = x + 3. Then oyu have to minus the 3 from both sides. so you'll have 8x - 11 = x. then you have to subtract 8x from both sides. -11 = -7x. then divid each side by -7 and you come out with 11/7 = X.

3(2x + 2) + 2(x - 7) = x + 3

Distribute first

(6x + 6) + (2x - 14) = x + 3

Combine like terms

8x - 8 = x + 3

Subtract x from both sides - Add 8 to both sides

7x = 11

x = 11 / 7

First distribute: 6x+6+2x-14=x+3

Add like terms: 8x-8=x+3

Subtract x from both sides and add 8: 7x=11

Divide both sides by 7: x= 11/7

There is your answer! x-11/7!!!!!

Simplify: 6x + 6 + 2x - 14 = x = 3. Combine like terms: 8x - 8 = 2x - 14. Subtract 2x from, and add 8 to, both sides. 6x = -6. Divide both sides by 6: x = -1.

well, it takes her 30 min, because the hands were together then exactly opposite, in order to do this, half an hour must have past. For the other part, if you think about the tic marks on a a clock, there are five marks between hours (after the four to the five.) So, each mark represents a 12 minute increment. Now, in order to for the hands to start out on top of eachother, she would have needed to start at least around 4: 20 (a little after actually). It can't be at the 36 minute tick mark, b/c then it's too late to complete the half hour, so the start is around 4:24 and the end 4:54 but you'll have to do the finer tuning yourself ^^

expand.

(6x + 6) + (2x - 14) = x + 3

combine like terms

8x -8 = x + 3

get x's on one side. [in this case subtract x on both sides]

7x - 8 = 3

get numbers on the other. [this case, add 8 on both sides]

7x = 11

divide by the coefficient of x [which is 7 in this case]

x = 11/7
