4x+5y=70
3x-2y=18

(x,y)=(10,6)

Step-by-step explanation:

Substitute the value of x into the equation {4x+ 5= 70

                                                                       {x= 6+ 2/3y

solve the equation 4(6+2/3y) +5y = 70

substitute the value of y into the equation y=6

solve the equation x=6 + 2/3 times 6

A possible solution is x= 10

Check the solution (x,y) = (10 ,6)

Simplify {4 times 10 + 5 times 6 =7

              {3 times 10 - 2 times 6 = 18

The ordered pair is a solution {70 = 70

                                                   {18 =18

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°
