4X Takeaway 10 equals 20+ 6X
Natasha2012 [34]
X= -15
First, we want to combine like terms.
4x-10=20+6x
Subtract 4x from both sides
-10=20+2x
Subtract 20 from both sides
-30=2x
Divide by 2 to isolate the variable
X= -15

Solve the system using any method.<br> x= - 4y+7<br> -2y+3x=9
Arte-miy333 [17]

The solution to the given system of equation is (25/7, 6/7)

<h3>System of equation</h3>

Given the system of equation expressed as:

x= - 4y+7 ........... 1

-2y+3x=9 ...........2

Substitute the equation 1 into 2 into have:

-2y + 3(-4y+7) = 9

-2y + 3(-4y) + 3(7) = 9

-2y - 12y + 21 = 9

Collect the like terms

-14y = 9- 21

-14y = -12

y = 6/7

Substitute y = 6/7 into equation 1;

x =-4y + 7

x = -4(6/7) + 7

x= -24/7 + 7

x = -24+49/7

x = 25/7

Hence the solution to the given system of equation is (25/7, 6/7)

In how many ways can a committee of 3 men and 2 women be formed from a group of 9 men and 10 ​women?
Setler [38]

Answer:

first you have to find the number of ways 3 men can be chosen, then the number of ways 2 women can be chosen, and then you need to multiply these numbers together to get the number of ways because multiplication will show the total arrangements possibilities. use combination since order does not matter.

number ways for 2 out of 10 women total: 10 choose 2= 45

number of ways for 3 out of 9 men total: 9 choose 3= 84

84x45= 3780

3780 total ways

number of ways
