What is the solution of the following system?

Given system:

-2x-y=1 (1)

-4x-2y=-1 (2)

2*(1) -(2)

-4x-2y +4x+2y = 2-(-1)

0=3   => there is no solution because the two lines (equations) are parallel and distinct (never meet), so no solution.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
