6p +2q = 14

2p -2q = -6

8p = 8

p = 1

Answer:

P= 1, q= 4

Step-by-step explanation:

3p + q = 7 -------------(1)

q=7-3p ------------------(1a)

2p- 2q= -6 -------------(2)

Substitute (1a) in (2)

We have :

2p - 2( 7- 3p) = -6

2p -14 + 6p = -6

8p= 14-6= 8

P= 8/8 =1

From, q=7 -3(1)

q= 7-3

q= 4

Answer:

First, you multiply 0.07 by 0.15

60 + (0.07) * (0.15)

60 + 0.0105

= 60.0105

I hope this helps!

Is x=2 a solution to the equation below? <br> 4(x-1)-3(x-2)=-8
Sonbull [250]

Answer:

No

Step-by-step explanation:

To find out if 2 is a solution, replace all the x's with 2.

4(2 - 1) - 3(2 - 2) =8

4(1) - 3(0) = 8

4 - 0 = 8

4 = 8

Nope!  False!  2 is not a solution.
