4x-2y=10
y=-2x-1
find the solution

Therefore the Final Solution is

Step-by-step explanation:

Given:

               ...............Equation ( 1 )

                  ................Equation ( 2 )

To Find:

x = ?

y = ?

Solution:

Substituting Equation  ( 2 ) in Equation ( 1 ) we get

Now Substituting x = 1 in Equation ( 2 ) we get

Therefore the Final Solution is

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
