-4(3k-6)-4k = -8k+24-4k
can yall solve this plz I want to go to sleep but my mom won't let me until I get my homework done

Answers

Answer:

0 (undefined)

Step-by-step explanation:

distribute on the left side first:

-4(3k-6)-4k

so -12k+24-4k

combine like terms

-16k+24

now the right side

-8k+24-4k

combine like terms

-12k+24

so it'll look like this

-16k+24=-12k+24

add -12k to the left

-4k+24=24

so then subtract 24

that'll leave you with 0

The ratio of money in Brian's wallet to Colin's wallet one day was 7:2.
Brian spent £39 that day.
Brian now had £4 less than Colin.
How much did they initially have altogether?

Answers

Answer:

£30

Step-by-step explanation:

Let Brian initially had money in his wallet = £x

and Colin had the money = £y

Since ratio of money in Brian's wallet to Colin's wallet was 5 : 1

Therefore,

⇒ x = 5y -------(1)

Brian spent £27 that day, so money left with him = £(x - 27)

After spending the money Brian had £3 less than Colin.

(x - 27) = (y - 3)

x = y + 27 - 3

x = y + 24 -------(2)

Now we equate the equations (1) and (2) for the value of x,

5y = y + 24

5y - y = 24

4y = 24

y = £6

From equation (2),

x = 6 + 24

x = £30

Therefore, Brian initially had £30.

i hope this helps

Answers

the answer would be x = 1

Answer:

x = 1

Step-by-step explanation:

1/2(8x-6) = -1/3(9x-12) distribute

4x-3 = -3x+4 add 3x to both sides

7x-3 = 4 add 3 to both sides

7x = 7 divide by 7 on both sides

x = 1
