Determine the value of x for which rls if<br> .<br> m2i = 80 - X; and<br> mz2 = 90 - 2x<br> .

Slav-nsk [51]

Answer:

x = 10

Step-by-step explanation:

For the lines to be parallel, the two angles must have the same measure:

80 - x = 90 - 2x

x = 10 . . . . . . . . . add 2x-80

The value of x must be 10 to make the lines parallel.

39. Solve this system: 3x+y=-7 . 4x-y=14A. (–1, 10)B. (1, –10)C. (–1, –10)D. no solution

valkas [14]

Given,

The linear pair of the equation is,

$\begin{gathered} 3x+y=-7 \\ 4x-y=14 \end{gathered}$

Required

The solution of the linear equation.

Taking the equation first as,

$\begin{gathered} 3x+y=-7 \\ y=-7-3x \end{gathered}$

Substituting the value of y in second equation then,

$\begin{gathered} 4x-y=14 \\ 4x+7+3x=14 \\ 7x+7=14 \\ 7x=7 \\ x=1 \end{gathered}$

Substituting the value of x in first equation then,

$\begin{gathered} 3x+y=-7 \\ 3(1)+y=-7 \\ y=-7-3 \\ y=-10 \end{gathered}$

Hence, the solution of the system is (1, -10).
