Answer:
Step-by-step explanation:
This root can be rewritten as:
Since 6487209 is a multple of 3, the expression can be rearranged as follows:
2162403 is also a multiple of 3, then:
720801 is a multiple of 3, then:
240267 is a multiple of 3, then:
80089 is a multiple of 283, then:
Answer:
(0, 4 ) and (2, - 4 )
Step-by-step explanation:
(2)
3x + 4y = 16 → (1)
- 3x + 2y = 8 → (2)
Adding (1) and (2) term by term will eliminate the x- term
0 + 6y = 24
6y = 24 ( divide both sides by 6 )
y = 4
Substitute y = 4 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(4) = 16
3x + 16 = 16 ( subtract 16 from both sides )
3x = 0 , then
x = 0
solution is (0, 4 )
(3)
2x - 4y = 20 → (1)
5x + 4y = - 6 → (2)
Adding (1) and (2) term by term will eliminate the y- term
7x + 0 = 14
7x = 14 ( divide both sides by 7 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (2)
5(2) + 4y = - 6
10 + 4y = - 6 ( subtract 10 from both sides )
4y = - 16 ( divide both sides by 4 )
y = - 4
solution is (2, - 4 )

Answer:
1.) x=6
2.)n=13
Step-by-step explanation:
1.)
-4x-3=-6x+9
−4x=−6x+9+3
−4x+6x=12
2x=12
x=12/2
<u>Answer:</u> <u>x=6
</u>
<u></u>
2.)
41-2n=2+n
41=2+n+2n
41=2+3n
41−2=3n
39=3n
39/3=n
13=n
<u>Answer:</u> <u>n=13
</u>
Answer:
Step-by-step explanation:
2c + h =16 <- 1
4c + 3h = 34 <-2
1 to 2
3[2c+h = 16]3
=6c +3h = 48 <-3
3 to 2
6c +3h = 48
- 4c + 3h = 34
-----------------------------
2c = 14
c= 7
substitue C=7 to equation 1
2(7) + h =16
14 + h = 16
h = 2
Therefore 7 and 2 is the answer
