Since there are 6 numbers on a die that makes it a 1/6 chance to roll a 4. So to roll 2 4's would be double. 2/12

2e - 3f = 4

Varvara68 [4.7K]

Answer:

The value of e is -1 and f is -2.

Step-by-step explanation:

The steps are :

$2e - 3f = 4 - - - (1)$

$2e - 5f = 8 - - - (2)$

$2e - 3f - 2e - ( - 5f) = 4 - 8$

$2f = - 4$

$f = - 4 \div 2$

$f = - 2$

$substitute \: f = - 2 \: into \: (1)$

$2e - 3( - 2) = 4$

$2e + 6 = 4$

$2e = 4 - 6$

$2e = - 2$

$e = - 2 \div 2$

$e = - 1$

Help that one side is 2x-2

bogdanovich [222]

Answer: x = 2/3

Step-by-step explanation:

Add all sides.

2x-2 + 2x - 2 + x + x =

6x - 4

Put " = 0 "

6x-4 = 0

Add 4 to both sides.

6x-4 = 0

+4 = +4

-------------------

6x=4

You get 6x = 4 because the 4 on the left side of the equals sign cancelled out!

NOW DIVIDE 6 FROM BOTH SIDES

6x = 4

/6 /6

-----------

x= 4/6

SIMPLIFY / REDUCE FRACTION

4/6 divided by 2 = 2/3

2/3 is the answer !
